gs101 oriole: peripheral block 1 (peric1) and i2c12 support

[André Draszik]

Hi,
   
This patch series implements support for the 2nd connectivity
peripheral block on gs101.
This block contains an additional 6 USI, 1 I3C and 1 PWM
interfaces/busses.

i2cdetect shows all expected devices on the one i2c bus that this patch
series enables.
Everything that's in scope in this series works also without the
clk_ignore_unused kernel command line argument.

While working on this, I noticed the existing peric0 support for gs101
has a couple issues. That explains why there are differences compared 
to it and a separate patch series will be sent to fix up peric0
support.

Cheers,
Andre'
