ARM: tegra: use correct audio CODEC on Jetson TK1

Jetson TK1 contains an RT5639 not an RT5640. While the two are extremely
similar and mostly compatible, we should still use the correct device
name in the device tree. I had meant to fix this before applying the
initial DT, but this issue slipped my mind.

ARM: tegra: jetson-tk1: don't set mux func for GPIOs

When a Tegra pin is configured as a GPIO, the selected mux function is
irrelevant. Since we don't need to set the function for those pins,
don't do it!

ARM: tegra: update Venice2 pinmux

This re-imports the entire Venice2 pinmux data from the board's master
spreadsheet, thus tieing it to the primary definition of what is correct
for this board.

This also applies the same change as the previous patch does for Jetson
TK1: When a Tegra pin is configured as a GPIO, the selected mux function
is irrelevant. Since we don't need to set the function for those pins,
don't do it!

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.

ARM: tegra: dalmore - Add DSI power supply

The 1.2V supply for CSI and DSI was previously marked always-on. This is
suboptimal because it prevents the supply from being disabled when there
is no activity in the display or capture paths that it powers.

Hook up the regulator to the DSI output and mark it as not always-on, so
that it will only be enabled when DSI actually needs it.
