[PATCH v2 21/30] mmc: rockchip_sdhci: Add initial support for RK3528

[Jonas Karlman]

Add initial support for SDHCI controller in RK3528.

Only MMC Legacy and MMC High Speed (52MHz) mode is supported after this,
more work is needed to get the faster HS200/HS400/HS400ES modes working.

Variant tap and delay num is copied from vendor Linux tag
linux-6.1-stan-rkr5.
