platform/x86: asus-wmi: Map 0x2a code, Ignore 0x2b and 0x2c events 

stable inclusion
from stable-v5.10.199
commit 6c3a72d4ae243a63f0208a5e669e63d60af55614
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9AWJ5

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6c3a72d4ae243a63f0208a5e669e63d60af55614



--------------------------------

commit 235985d1 upstream.

Newer Asus laptops send the following new WMI event codes when some
of the F1 - F12 "media" hotkeys are pressed:

0x2a Screen Capture
0x2b PrintScreen
0x2c CapsLock

Map 0x2a to KEY_SELECTIVE_SCREENSHOT mirroring how similar hotkeys
are mapped on other laptops.

PrintScreem and CapsLock are also reported as normal PS/2 keyboard events,
map these event codes to KE_IGNORE to avoid "Unknown key code 0x%x\n" log
messages.
