[ Upstream commit f82bf3c5796e1630d553669fb451e6c9d4070512 ]
This driver uses various OF-specific functions and depends on phandle
parsing. There's no reason to make it available to non-OF systems so add
a relevant dependency switch to its Kconfig entry.

This adds the power sequencing driver for the PMU modules present on the
Qualcomm WCN Bluetooth and Wifi chipsets. It uses the pwrseq subsystem
and knows how to match the sequencer to the consumer device by verifying
the relevant properties and DT layout. Using this driver will allow the
BT and WLAN drivers to respect the required delays between enabling the
two modules.

Implement the power sequencing subsystem allowing devices to share
complex powering-up and down procedures. It's split into the consumer
and provider parts but does not implement any new DT bindings so that
the actual power sequencing is never revealed in the DT representation.
