Rervision A33-Vstar is an evaluation board for their A33-Core1 A33-based
SoM.
Add support for it.
Fastboot support is enabled for flashing the eMMC included within the
SoM, and R8152 Ethernet is enabled for the evaluation board's onboard
USB-to-Ethernet.
The device tree files are from Linux v6.13-rc1, with PMIC interrupt
patched to match the r_intc node in U-Boot.
