it83xx: Add a config option for enabling mouse LDN

Browse Source 
Not all boards using ITE83XX use mouse LDN. This change adds a config
option to allow boards to explicity enable this device. Currently,
this device is enabled only for glkrvp_ite and it83xx_evb. It is
disabled for reef_ite and bip.
