Adjusts the report descriptor for N-Key devices to
make the output count 0x01 which completely avoids
the need for a block of filtering.

Some of the n-key stuff is old and outdated, so
make asus_kbd_init() generic to use with other
report ID and remove rog_nkey_led_init().

A handful of buttons on the ROG Ally are not actually part of the xpad
device and are instead keyboard keys (a typical use of the MCU that asus
uses). We attach a group of F<num> key codes which aren't used much and
which the handheld community has already accepted as defaults here.
