hwdb: 60-keyboard:: Update Dell Privacy Micmute Hotkey Map

Dell new Privacy feature provide new hardware level privacy
protect for users
This patch remaps scancode 0x120001 to key code F20 micmute
The old matching string cannot cover some other Dell products
which have the privacy feature,expand the string to all the system
that can load the privacy driver,privacy driver already detect the
system if it can support this feature. So here we can safely just
map the micmute key to scancode 0x120001
