Joshua Cov b2d0b7a061 keyboard: Use BIOS Keyboard variable to set Numlock
The PC BIOS does provide a NUMLOCK flag containing the desired state
of this LED. This patch sets the current state according to the data
in the bios.

[ hpa: fixed __weak declaration without definition, changed "inline"
  to "static inline" ]
