hw/sd/sdcard: Remove SEND_DSR dead case (CMD4)

The CSD::CSR_IMP bit defines whether the Driver Stage
Register (DSR) is implemented or not. We do not set
this bit in CSD:

    static void sd_set_csd(SDState *sd, uint64_t size)
    {
        ...
        if (size <= SDSC_MAX_CAPACITY) { /* Standard Capacity SD */
            ...
            sd->csd[6] = 0xe0 |     /* Partial block for read allowed */
                ((csize >> 10) & 0x03);
            ...
        } else {                    /* SDHC */
            ...
            sd->csd[6] = 0x00;
            ...
        }
        ...
    }

The sd_normal_command() switch case for the SEND_DSR
command do nothing and fallback to "illegal command".
Since the command is mandatory (although the register
isn't...) call the sd_cmd_unimplemented() handler.

hw/gpio/aspeed: Add reg_table_count to AspeedGPIOClass

ASan detected a global-buffer-overflow error in the aspeed_gpio_read()
function. This issue occurred when reading beyond the bounds of the
reg_table.

To enhance the safety and maintainability of the Aspeed GPIO code, this commit
introduces a reg_table_count member to the AspeedGPIOClass structure. This
change ensures that the size of the GPIO register table is explicitly tracked
and initialized, reducing the risk of errors if new register tables are
introduced in the future.

docs: document special exception for machine type deprecation & removal

This extends the deprecation policy to indicate that versioned machine
types will be marked deprecated after 3 years, and then subject to
removal after a further 3 years has passed.

hw: skip registration of outdated versioned machine types

This calls the MACHINE_VER_DELETION() macro in the machine type
registration method, so that when a versioned machine type reaches
the end of its life, it is no longer registered with QOM and thus
cannot be used.

The actual definition of the machine type should be deleted at
this point, but experience shows that can easily be forgotten.
By skipping registration the manual code deletion task can be
done at any later date.

include/hw: temporarily disable deletion of versioned machine types

The new deprecation and deletion policy for versioned machine types is
being introduced in QEMU 9.1.0.

Under the new policy a number of old machine types (any prior to 2.12)
would be liable for immediate deletion which would be a violation of our
historical deprecation and removal policy

Thus automatic deletions (by skipping QOM registration) are temporarily
gated on existance of the env variable "QEMU_DELETE_MACHINES" / QEMU
version number >= 10.1.0. This allows opt-in testing of the automatic
deletion logic, while activating it fully in QEMU >= 10.1.0.

This whole commit should be reverted in the 10.1.0 dev cycle or shortly
thereafter.

include/hw: add macros for deprecation & removal of versioned machines

Versioned machines live for a long time to provide back compat for
incoming migration and restore of saved images. To guide users away from
usage of old machines, however, we want to deprecate any older than 3
years (equiv of 9 releases), and delete any older than 6 years (equiva
of 18 releases).

To get a standardized deprecation message and avoid having to remember
to manually add it after three years, this introduces two macros to be
used by targets when defining versioned machines.

* MACHINE_VER_DEPRECATION(major, minor)

  Automates the task of setting the 'deprecation_reason' field on the
  machine, if-and-only-if the major/minor version is older than 3 years.

* MACHINE_VER_DELETION(major, minor)

  Simulates the deletion of by skipping registration of the QOM type
  for a versioned machine, if-and-only-if the major/minor version is
  older than 6 years.

By using these two macros there is no longer any manual work required
per-release to deprecate old machines. By preventing the use of machines
that have reached their deletion date, it is also not necessary to
manually delete machines per-release. Deletion can be batched up once a
year or whenever makes most sense.

hw/i386: convert 'q35' machine definitions to use new macros

This changes the DEFINE_Q35_MACHINE macro to use the common
helpers for constructing versioned symbol names and strings,
bringing greater consistency across targets.

The added benefit is that it avoids the need to repeat the
version number thrice in three different formats in the calls
to DEFINE_Q35_MACHINE.

Due to the odd-ball '4.0.1' machine type version, this
commit introduces a DEFINE_Q35_BUGFIX helper, to allow
defining of "bugfix" machine types which have a three
digit version.
