ddr: add LPDDR2 data from JESD209-2
add LPDDR2 data from the JEDEC spec JESD209-2. The data
includes:
1. Addressing information for LPDDR2 memories of different
densities and types(S2/S4)
2. AC timing data.
This data will useful for memory controller device drivers.
Right now this is used by the TI EMIF SDRAM controller
driver.
