soc: renesas: rcar-sysc: Fix power domain control after system resume
To control power to a power domain, the System Controller (SYSC) needs
the corresponding interrupt source to be enabled, but masked, to prevent
the CPU from receiving it.
Currently this is handled in the driver's probe() routine, and set up
for every domain present, even if it will not be controlled directly by
SYSC (CPU domains are powered through the APMU on R-Car Gen2 and later).
On R-Car Gen3, PSCI powers down the SoC during system suspend, thus
losing any configured interrupt state. Hence after system resume, power
domains not controlled through the APMU (e.g. A3IR, A3VC, A3VP) fail to
power up.
Fix this by replacing the global interrupt setup in the probe() routine
by a domain-specific interrupt setup in rcar_sysc_power(), where the
domain's power is actually controlled. This brings the code more in
line with the flowchart in the Hardware User's Manual.

tipc: fix link re-establish failure
When a link failure is detected locally, the link is reset, the flag
link->in_session is set to false, and a RESET_MSG with the 'stopping'
bit set is sent to the peer.
The purpose of this bit is to inform the peer that this endpoint just
is going down, and that the peer should handle the reception of this
particular RESET message as a local failure. This forces the peer to
accept another RESET or ACTIVATE message from this endpoint before it
can re-establish the link. This again is necessary to ensure that
link session numbers are properly exchanged before the link comes up
again.
If a failure is detected locally at the same time at the peer endpoint
this will do the same, which is also a correct behavior.
However, when receiving such messages, the endpoints will not
distinguish between 'stopping' RESETs and ordinary ones when it comes
to updating session numbers. Both endpoints will copy the received
session number and set their 'in_session' flags to true at the
reception, while they are still expecting another RESET from the
peer before they can go ahead and re-establish. This is contradictory,
since, after applying the validation check referred to below, the
'in_session' flag will cause rejection of all such messages, and the
link will never come up again.
We now fix this by not only handling received RESET/STOPPING messages
as a local failure, but also by omitting to set a new session number
and the 'in_session' flag in such cases.

Commit

moved the location of 'dtbs_install' target which caused dtbs to not be
installed when building debian package with 'bindeb-pkg' target. Update
the builddeb script to use the same logic that determines if there's a
'dtbs_install' target which is presence of the arch dts directory. Also,
use CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF as that's a better
indication of whether we are building dtbs.
This commit will also have the side effect of installing dtbs on any
arch that has dts files. Previously, it was dependent on whether the
arch defined 'dtbs_install'.
