soc/amd: Use SPDX for GPL-2.0-only files Done with sed and God Lines. Only done for C-like code for now.

soc/amd/picasso: Create picasso as a copy of stoneyridge So that everyone can see what's being updated from stoney, we're starting with a direct copy of the stoney directory. There are arguments both for and against doing it this way, but I believe This the most transparent way. We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated. Other than that change, this is an exact copy of the stoneyridge SOC directory which will be updated in the follow-on commits in the patch train.

soc/amd/picasso: Update UARTs Add a function to uart.c to ensure the right IOMux settings are programmed for the console UART. Update Kconfig to reflect the new addresses. Give the user the ability to downclock the UARTs' refclock to 1.8342MHz. Add the abiltiy to use an APU UART at a legacy I/O address. Update the AOAC register configuration for the two additional UARTs.

Change all clrsetbits_leXX() to clrsetbitsXX() This patch changes all existing instances of clrsetbits_leXX() to the new endian-independent clrsetbitsXX(), after double-checking that they're all in SoC-specific code operating on CPU registers and not actually trying to make an endian conversion. This patch was created by running sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g' across the codebase and cleaning up formatting a bit.
