x86/config: Revamp configuration for MID devices

Browse Source 
This follows on from the patch applied in 3.2rc1 which creates
an INTEL_MID configuration. We can now add the entry for
Medfield specific code. After this is merged the final patch
will be submitted which moves the rest of the device Kconfig
dependancies to MRST/MEDFIELD/INTEL_MID as appropriate.

Medfield is Intel's Low Power Intel Architecture (LPIA) based Moblin
Internet Device(MID) platform.
Unlike standard x86 PCs, Medfield does not have many legacy devices
nor standard legacy replacement devices/features. e.g. Medfield does
not contain i8259, i8254, HPET, legacy BIOS, most of the io ports.
