The wcd9310 codec driver which is slimbus slave can access codec
registers when slimbus is suspended.
This can cause register read/write failure.
Fix to make sure slimbus is awake before accessing wcd9310 codec's
registers through slimbus.

switches in PMIC 8018, 8038, and 8921 core drivers. This will

When a non requested interrupt triggers, the genirq ends up calling
mask or mask_ack callback. This callback is expected to mask that
interrupt so it doesn't trigger us further.
There is a bug in the pm8xxx-irq driver where config[] entry for an
unrequested irq remains empty. So the mask or the mask_ack callback
ends up masking 0th interrupt.
Fix the mask and mask_ack callback to check if config[] is empty, if
so fill it in right then and mask the irq.

Add a new API, pm8xxx_preload_dVdd, which will preload the dVdd
regulator on PMIC PM8901 chips during off state. This can help

cost of additional off state current draw.
This API should only be called if dVdd startup issues are
