pckbd: return 'keyboard enabled' on read input port command

Browse Source 
Bit 7 of Input Port is the keyboard inhibit switch.
0 means keyboard inhibited, while 1 means keyboard enabled.

Incidentaly, this also fixes an error encountered while booting
an Award BIOS: "Keyboard is locked out - Unlock the key".
