MLK-11387-2 ARM: imx: add imx7d lpddr2 support
i.MX7D LPDDR2 board has same flow of suspend/resume
and busfreq with LPDDR3, the only difference is the
DRAM init script which is done in u-boot.
This patch adds suspend/resume and busfreq support
for i.MX7D LPDDR2, tested on i.MX7D 19x19 LPDDR2 board.
