power: sequencing: qcom-wcn: explain why we need the WLAN_EN GPIO hack
With the recent rework of the PCI power control code, the workaround for
the wlan-enable GPIO - where we don't set a default (low) state in the
power sequencing driver, but instead request the pin as-is - should no
longer be needed but some platforms still fail to probe the WLAN
controller. This is caused by the Qcom PCIe controller and needs a
workaround in the controller driver so add a FIXME to eventually remove
the hack from this driver once this is done.

power: sequencing: qcom-wcn: improve support for wcn6855
WCN6855 (also known as QCA6490) is similar to the already supported
QCA6390 but takes in two more supplies so add a new vregs list for it.
On sm8450-hdk it also requires a short assert of the xo-clk pin so add
handling for it in a dedicated unit.
As we now have a separate set of targets for this variant, store the
pointer to the targets struct associated with a model in the device
match data.

power: pwrseq: add a driver for the PMU module on the QCom WCN chipsets
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.
