Configure the IPCC summary IRQ as wakeup capable interrupt.
IPCC interrupt needs to wake up the device from low power
modes when wakeup capable event is generated from remote
subsystem.

Since the tcs_in_use flag is authoritative enough to determine the
idleness of the TCS, avoid reading the register redundantly.

For RSCs that have sleep & wake TCS but no dedicated active TCS, wake
TCS can be re-purposed to send active requests. Once the active requests
are sent and response is received, the active mode configuration needs
to be cleared so that controller can use wake TCS for sending wake
requests in 'solver' state while executing low power modes.

Controllers may be in 'solver' state, where they could be in autonomous
mode executing low power modes for their hardware and as such are not
available for sending active votes. Device driver may notify RPMH API
that the controller is in solver mode and when in such mode, disallow
requests from platform drivers for state change using the RSC.

When triggering a TCS to send its contents, reading back the trigger
value may return an incorrect value. That is because, writing the
trigger may raise an interrupt which could be handled immediately and
the trigger value could be reset in the interrupt handler.
A write_tcs_reg_sync() would read back the value that is written and try
to match it to the value written to ensure that the value is written,
but if that value is different, we are stuck in loop forever.
