Add amd_sof_acp7x_suspend() and amd_sof_acp7x_resume() for ACP7.B/7.F

The interrupt is requested with IRQF_SHARED so probably worth double
checking if the interrupt handler is safe to run while the suspend and
resume callbacks are running, I see we reset the device during suspend
so there might be some risk of corrupted register reads?
There won't be any corrupted register reads when acp reset sequence
is executed,  all the acp registers are set to default values. i.e Interrupt
control registers are disabled. This sequence ensures that till interrupt
masks are enabled during resume sequence, no interrupt will be asserted
for ACP IP.
