Universal Serial Interface (USI) supports three serial protocol
like uart, i2c and spi. ExynosAutov920 has 18 instances of USI.
Add spi nodes for all the instances.

Add UFS Phy for ExynosAutov920
Like ExynosAutov9, this also uses fixed-rate clock nodes until clock driver
has been supported. The clock nodes are initialized on bootloader stage
thus we don't need to control them so far.
Changes from v4:
- Place entry in correct order instead of appending to the end.

Add CPU caches information to its dt nodes so that the same is
available to userspace via sysfs. This SoC has 64/64 KB I/D cache and
256KB of L2 cache for each core, 2 MB of shared L3 cache for each quad
cpu cluster and 1 MB of shared L3 cache for the dual cpu cluster.

Samsung ExynosAutov920 is ARMv8-based automotive-oriented SoC.
It has AE(Automotive Enhanced) IPs for safety.
* Cortex-A78AE 10-cores
* GIC-600AE
This is minimal support for ExynosAutov920 SoC.
* Enumerate all pinctrl nodes
* Enable Chip-Id
* Serial0 for console
* PWM
Since the clock driver is not yet implemented, it is supported as
fixed-clock.
