[00/13] hid: playstation: add DualShock4 support

Hi,

Last year, we introduced hid-playstation as the start of a new driver
for officially supported PlayStation peripherals. The driver initially
only supported DualSense devices, but we promised to also bring support
for at least DualShock4 as well.

This patch series adds DualShock4 support to hid-playstation. It should
be considered a brand new driver written from scratch in the same design
as hid-playstation. The driver is more documented and uses structures
instead of byte offsets with magical values. The driver should be more
clear and easier to follow. A few little sections of code cary over, which
Sony contributed before for sensor calibration or dongle support.

Functionality wise the driver is equivalent to hid-sony. The only subtle
change is in the naming of the lightbar LEDs. Previously they used a naming
scheme like '<mac_address>:<color>", which doesn't follow the LED class standards.
The new scheme uses '<device_name>:<color>' (e.g. input10:red), which is more
compliant. Due to backwards compatibility in particular for Android, we couldn't
make it fully compliant. Nor were we able to use the new multicolor LED class.

Aside from the LED code, the other features behave the same way. The hid-tools
tests all pass as well. One small change is that we use a different HID report
0x12 to get the MAC address in USB mode. This report is the official one even
though other ones can get the info too, but e.g. clone devices don't tend to
support it.

Thanks,

Hi Roderick,

this is now queued in hid.git#for-6.2/sony.

Thanks for all the work on this,
