With the MMC_SPEED_MODE_SET Kconfig option enabled.
Writing to eMMC using HS200 mode work more reliably than slower modes on
RK35xx boards. Enable MMC_HS200_SUPPORT Kconfig option by default to
prefer use of HS200 mode on RK356x and RK3588.

Changes in v2:
- Imply MMC_HS200_SUPPORT and SPL_MMC_HS200_SUPPORT in arch Kconfig
instead of adding to each boards defconfig
- R-b tags not collected because of above change
- Combine changes for rk356x and rk3588 in one patch
- Update commit message

MMC_SDHCI_ROCKCHIP is also required for eMMC on RK3399, which would
change the current default, at the very least for Puma RK3399.
Doing a:
rg -lU --multiline-dotall 'RK3399.*MMC_HS.*' configs/
Only returns:
configs/evb-rk3399_defconfig
configs/pinebook-pro-rk3399_defconfig
and there are 29 defconfigs for RK3399-based boards right now, so maybe
that's a bit too big of a change?
Cheers,
Quentin
