MLK-11238 imx: mx7d fix usdhc pad settings
To CD/VSELECT/RST, should use same pad settings with USDHC_PAD_CTRL,
because default NO_PAD_CTRL's settings is 100K Pull-Down. But, we need
pull-up for CD/VSELECT/RST.
Also some board provides external pull-down/up, we'd better use internal
pull-up for these pad settings.
To mx7d_12x12_lpddr3_arm2:
If no card plugged in, "mmc dev 1" will show "Card did not respond to
voltage select". After apply this patch, it will show "MMC: no card present".
To mx7dsabresd:
Alougth without this patch, if no card plugged in sd1, still correct msg
"MMC: no card present", anyway we'd better use pull-up.
