mmc: tegra: disable UHS modes

Program TEGRA_SDHCI_VENDOR_MISC_CTRL so that UHS modes aren't advertised
in SDHCI_CAPABILITIES_1.  While the Tegra SDHCI controller does support
these modes, they require Tegra-specific tuning and calibration routines
which the driver does not support yet.

mmc: tegra: fix reporting of base clock frequency

Tegra SDHCI controllers, by default, report a base clock frequency
of 208Mhz in SDHCI_CAPABILTIES which may or may not be equal to the
actual base clock frequency.  While this can be overridden by setting
BASE_CLK_FREQ in VENDOR_CLOCK_CTRL on Tegra30 and later SoCs, just
set SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN and supply a get_max_clock()
callback to get the actual rate of the base clock.

WIP: ARM: tegra: start work on Venice2 touchpad

Also added ISL light sensor to test I2C bus. Need to split this out
into a separate patch.

Import downstream driver from chromeos-3.10 so it initializes at all.

S-o-b: FIXME: a lot of downstream patches...
