[Marshall Dawson (Code Review)]

Hello Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/36117

to look at the new patch set (#2).

Change subject: soc/amd/picasso: Add audio processor
......................................................................

soc/amd/picasso: Add audio processor

Add a driver that can properly configure the pads needed to run the
correct audio mode.  I2S requires the 48M oscillator enabled
regardless of an external connection.
