memory: emif: add basic infrastructure for EMIF driver
EMIF is an SDRAM controller used in various Texas Instruments
SoCs. EMIF supports, based on its revision, one or more of
LPDDR2/DDR2/DDR3 protocols.
Add the basic infrastructure for EMIF driver that includes
driver registration, probe, parsing of platform data etc.
