On DB845c board WiFi/BT chip can use both RF channels/antennas, so add
vddch1-supply property.

Use bus-pwrseq device tree node to power up the devices on the bus. This
is to be rewritten with the proper code parsing the device tree and
powering up individual devices.

Power sequencing for Qualcomm WiFi+BT chipsets are being reworked to use
pwrseq rather than individually handling all the regulators. Add support
for pwrseq to ath10k SNOC driver.

Add support for the bluetooth part of the QCA6391 BT+WiFi chip present
on the RB5 board. WiFi is not supported yet, as it requires separate
handling of the PCIe device power.

This is the second RFC on the proposed power sequencer subsystem. This
is a generification of the MMC pwrseq code. The subsystem tries to
abstract the idea of complex power-up/power-down/reset of the devices.
To ease migration to pwrseq and to provide compatibility with older
device trees, while
While we are waiting for all users of wcn399x-bt to be converted to the
pwrseq declaration in the device tree, provide support for the pwrseq
fallback: if the regulators are declared in the device itself, create
pwrseq instance. This way the hci_qca driver doesn't have to cope with
old and new dts
Drop old MMC pwrseq code and use new pwrseq subsystem instead.
Individual drivers are already ported to new subsystem.

Power sequencer support requires changing device tree. To ease migration
to pwrseq, add support for pwrseq 'fallback': let the power sequencer
driver register special handler that if matched will create pwrseq
instance basing on the consumer device tree data.

Basing on MMC's pwrseq support code, add separate power sequencer
subsystem. It will be used by other drivers to handle device power up
requirements.

Add support for power sequencer used in the Qualcomm BT+WiFi SoCs. They
require several external volate regulators and some of them use separate
BT and WiFi enable GPIO pins. This code is mostly extracted from the
hci_qca.c bluetooth driver and ath10k WiFi driver. Instead of having
each of them
