bdb2c52a6e ARM: tegra: Update sound node clocks in device tree
clk_out_1, clk_out_2, and clk_out_3 are part of Tegra PMC block but were
previously erroneously provided by the clock and reset controller.

clk_out_1 is dedicated for audio mclk on Tegra30 through Tegra210.

This patch updates device tree sound node to use clk_out_1 from the PMC
provider as mclk and uses assigned-clock properties to specify clock
parents for clk_out_1 and extern1.

b57d6b996e ARM: tegra: apalis_t30: support v1.1 hardware revision
Support the V1.1 hardware revisions with the following change:

Changed power rail for MMC1 interface to a 3.3V/1.8V switchable rail in
order to be able to run UHS SD cards in ultra high speed 1.8V mode.

[  207.502011] mmc2: host does not support reading read-only switch,
 assuming write-enable
