[v1,0/9] Add PERIC0/1 support for Exynos 990

Message

This patch series introduces support for
the PERIC0 and PERIC1 blocks in the Exynos 990 SoC.
It includes devicetree bindings, clock definitions,
and driver support for the following components:

- Universal Serial Interface (USI):
  - Adds samsung,exynos990-usi compatible
    for defining USI nodes in PERIC0/1.
  - Supports UART, SPI, and I2C modes.
  - Defines all 18 USI nodes in the Exynos 990 device tree.

- SPI (Serial Peripheral Interface):
  - Adds `samsung,exynos990-spi` compatible.
  - Implements SPI port configuration data.
  - Some controllers (SPI 8, 9, and 10) use a 256 bytes FIFO depth 
    instead of the usual 64 bytes.

- HSI2C (High-Speed I2C):
  - Adds `samsung,exynos990-hsi2c` compatible for Exynos 990.  

- Clock Management Unit (CMU) for PERIC0/1:
  - Adds clock definitions for USI and I2C peripherals.  
  - CMU_PERIC0/1 clocks are not marked as critical.  

This has been tested on the Samsung Galaxy S20 FE (r8s),
where USI and SPI interfaces are confirmed to be functional.
