MLK-12436-16: imx: mx6sxsabresd: update board and header

Align with imx_v2016.03.
Add emmc support which needs board rework.
Add I2C2.
Update pmic settings.
Add bmode.
Move partial code from board_early_init_f to board_init.
Add PCI power and reset GPIO and disable PCI at default.
Update QSPI settings.
