Subject: [PATCH] HID: hid-sony: Fix DS4 controller reporting rate issues

 This commit removes the cap on the DualShock 4 controller reporting
rate when connected using Bluetooth. The previous value of '0xB0'
capped the rate to only 20.83 Hz which many userspace utilities
mistook as a sign of a bad signal. Since a 'B' and an '8' can look
similar it's possible that someone mistook the one for another.
The new value of '0x80' enables the full 1000 Hz peak reporting
rate that the controller is capable of.
