arm64: dts: exynos: drop unsupported UFS properties in ExynosAutov9 SADK

There is no vcc-fixed-regulator property for UFS nodes:

exynosautov9-sadk.dtb: ufs@17e00000: Unevaluated properties are not allowed ('vcc-fixed-regulator' was unexpected)

arm64: dts: exynosautov9: prepare usi0 changes

Before adding whole USI nodes, this applies the changes of usi0 in
advance. To be the usi0 and serian_0 nodes as SoC default, some
properties should be moved to exynosautov9-sadk.dts.

arm64: dts: exynos: move XTCXO clock frequency to board in Exynos Auto v9

The external oscillator - XTCXO - is an input to the SoC. It is defined
in the Exynos Auto v9 SoC DTSI, because all boards will provide it and
clock controller bindings expect it, however the actual frequency of the
clock should be determined by the board.

arm64: dts: exynos: convert serial_0 to USI on ExynosAutov9

According to USI v2 driver change[1], serial_0 node should be converted to
use the USI node hierarchy. syscon_peric0 will be used as a syscon node
to control the USI00_USI_SW_CONF register.
This also changes the serial node name from uart@ to serial@.
