Samsung SoC drivers for v6.18

1. Google GS101:
   Enable CPU Idle, which needs programming C2 idle hints
   via ACPM firmware (Alive Clock and Power Manager).  The patch
   introducing this depends on 'local-timer-stop' Devicetree property,
   which was merged in v6.17.

   Fix handling error codes in ACPM firmware driver when talking to
   PMIC.

2. Exynos2200: Add dedicated compatible for serial engines (USI).
