This reverts commit 1f902f8636e4 ("HID: playstation: report DualSense
hardware and firmware version.")
There is currently an ongoing discussion on linux-leds LKML,
and so to give us more room, we need to revert those related
LEDs patches from linux-next.
To have a cleaner merge with the new version, we also revert
all patches on top of the LED ones.
This is not a big deal, they are still not pushed to Linus.
