mmc: tegra: use 1.8V quirk only on affected instances
The 1.8V quirk also affected the internal eMMC which disabled newer
modes such as SDR50, SDR104 and DDR50. This in turn lead to an
out of spec usage since the clock was still 50MHz.
By creating a no_1v8 field in the platform data we can now enable
this work around on a per-instance basis. Hence we enable the
quirk only on the controllers which are connected to the external
SD-slots.
