HID: asus: Filter spurious HID vendor codes on ROG laptops 

On Asus ROG laptops, several HID vendor usage codes (0xea, 0xec, 0x02,
0x8a, 0x9e) are sent during normal operation without a clear purpose,
generating unwanted "Unmapped Asus vendor usagepage code" warnings in
dmesg.

Add definitions for these codes and filter them out in asus_raw_event()
to prevent kernel log spam.

Tested on Asus ROG series laptops.
