HID: rakk: add support for Rakk Dasig X side buttons
The Rakk Dasig X gaming mouse has a faulty HID report descriptor that
declares USAGE_MAXIMUM=3 (buttons 1-3) while actually sending 5 button
bits (REPORT_COUNT=5). This causes the kernel to ignore side buttons
(buttons 4 and 5).
Fix by patching the descriptor to set USAGE_MAXIMUM=5 in the
report_fixup callback.
The mouse uses Telink vendor ID 0x248a with three product IDs for USB
direct (0xfb01), wireless dongle (0xfa02), and Bluetooth (0x8266)
connection modes. All three variants have the same bug at byte offset 17.
