ASoC: tegra-alt: Add support for supermodule on Galen/Rey

Browse Source 
Add support for the E2614 supermodule on the Tegra194 Galen and Rey
platforms. Note that on Galen and Rey, because the 'aud_mclk' is not
available on the 40-pin header and the clock available on the 40-pin
header, 'extperiph4', cannot generate the frequencies needed for the
various sampling rates supported, we use the I2S bit-clock to drive
the RT565x codec PLL. Hence, the name of the DAI link for the codec
is 'rt565x-codec-sysclk-bclk1' to indicate that we need to configure
the codec to use BCLK1 to drive the codec's internal PLL.
