[PATCH v2 0/2] rockchip: Add support for ROCK 5B+

[Jonas Karlman]

This series add support for the ROCK 5B+ variant to the existing
rock5b-rk3588 defconfig taget.

The ROCK 5B+ variant is detected based on DRAM type (LPDDR5) and SARADC
channel 5, the read out value is expected to be close to 4095 (1.8v) on
5B+ variants.

Features tested on a ROCK 5B+ v1.2:
- SD-card boot
- eMMC boot
- SPI flash boot
- PCIe/NVMe
- Ethernet
- USB/TCPM

Changes in v2:
- Add a DRAM type check to detected ROCK 5B+ variant
- Drop device tree patches merged with the v6.16-dts sync
