Add description for the SDHCI v5.1 eMMC controller on rk3399. Fix it to
200 MHz, to support all supported timing modes.
Note that 'rockchip,rk3399-sdhci-5.1' is not documented; we presumably
have a compliant Arasan controller, but let's have a rockchip property
as the canonical backup/precautionary measure. Per Heiko's previous
suggestion, let's not clutter the arasan doc with it.
