soc/apollolake: Add lpc device driver

A dedicated pci device driver required for LPC devices as the legacy
IO range need to be included to avoid IO resource confilict. Blindly
set to 0~0x1000 to also avoid the IO resource of COMA/COMB/LPT/FDD
and LPC.Without this driver system will have assertion on load
RTC DXE driver in UEFI payloads.
