These devices are required for audio sub system and current patch
ensures probe path of these devices gets tested. Later sound card
support would be added which can use these devices at runtime.

The PWM on Tegra210 can run at a maximum frequency of 48 MHz and cannot
reach the minimum period is 5334 ns. The currently configured period of
4880 ns is not within the valid range, so set it to 8000 ns. This value
was taken from the downstream DTS files and seems to work fine.

arm64: tegra: Fix Jetson Nano GPU regulator

There are a few issues with the GPU regulator defined for Jetson Nano
which are:

1. The GPU regulator is a PWM based regulator and not a fixed voltage
regulator.
2. The output voltages for the GPU regulator are not correct.
3. The regulator enable ramp delay is too short for the regulator and
needs to be increased. 2ms should be sufficient.
4. This is the same regulator used on Jetson TX1 and so make the ramp
delay and settling time the same as Jetson TX1.
