Drop legacy data for dra7 and omap4/5 for genpd support for v5.13
Similar to what we have already done for am3 and 4, we can now boot dra7,
omap4, and omap5 with devicetree data and genpd without legacy SoC specific
built-in data.
Let's drop the legacy data for these SoCs, and the related "ti,hwmods"
custom devicetree property. As with these changes we now expect to have
complete devicetree data, let's also warn in the case if an old devicetree
data is noticed. And with the warning provided, there should not be any
need to delay dropping the legacy data as it just unnecessarily complicates
things.
The main reasons for dropping the legacy data is to avoid the burden of
maintaining a mixed boot process where both legacy built-in data and
devicetree data are needed. And we can now use standard reset driver,
genpd, and simple-pm-bus features.
These patches are based on the related devicetree changes to add the
missing interconnect target module configuration for these SoCs.

ARM: s3c: Use pwm_get() in favour of pwm_request() in RX1950
pwm_request() is deprecated because (among others) it depends on a global
numbering of PWM devices. So register a pwm_lookup to pick the right PWM
device (identified by provider and its local id) and use pwm_get().
Before this patch the PWM #1 was used. This is provided by the
samsung-pwm device which is the only PWM provider on this machine. The
local offset is 1, see also commit
c107fe904a10 ("ARM: S3C24XX: Use PWM
lookup table for mach-rx1950") with a similar conversion for PWM #0.
As a follow up specify the period only once and symmetrically use pwm_put()
instead of pwm_free() to drop the reference.

PCI: pci-dra7xx: Prepare for deferred probe with module_platform_driver
After updating pci-dra7xx driver to probe with ti-sysc and genpd, I
noticed that dra7xx_pcie_probe() would not run if a power-domains property
was configured for the interconnect target module.
Turns out that module_platform_driver_probe uses platform_driver_probe(),
while builtin_platform_driver uses platform_driver_register().
Only platform_driver_register() works for deferred probe as noted in the
comments for __platform_driver_probe() in drivers/base/platform.c with a
line saying "Note that this is incompatible with deferred probing".
With module_platform_driver_probe, we have platform_driver_probe() produce
-ENODEV error at device_initcall() level, and no further attempts are done.
Let's fix this by using module_platform_driver instead.
Note this is not an issue currently as we probe devices with simple-bus,
and only is needed as we start probing the device with ti-sysc, or when
probed with simple-pm-bus.
Note that we must now also remove __init for probe related functions to
avoid a section mismatch warning.

bus: ti-sysc: Check for old incomplete dtb
Let's be nice and show an error on the SoCs about old imcomplete devicetree
if the dtb is still using "simple-bus" instead of "simple-pm-bus" for the
root OCP node.

We want to probe l4_wkup and l4_cfg interconnect devices first to avoid
issues with missing resources. Otherwise we attempt to probe l4_per

renumbering of the MMC devices for example.

bus: ti-sysc: Fix initializing module_pa for modules without sysc register
We have interconnect target modules with no known registers using only
clocks and resets, but we still want to detect them based on the module
IO range. So let's call sysc_parse_and_check_child_range() earlier so we
have module_pa properly initialized.
