[00/13] GS101 Oriole: CMU_PERIC0 support and USI updates

Message

Add support for PERIC0 clocks. Use them for USI in serial and I2C
configurations. Tested the serial at different baudrates (115200,
1M, 3M) and the I2C with an at24 eeprom, all went fine.

Apart of the DT and defconfig changes, the patch set spans through the tty
and clk subsystems. The expectation is that Krzysztof will apply the whole
series through the Samsung SoC tree. If the tty and clk subsystem
maintainers can give an acked-by or reviewed-by on the relevant patches
that would be most appreciated!

Thanks!
