rockchip: rk35xx: Enable eMMC HS200 mode by default
Testing has shown that writing to eMMC using a slower mode then HS200
typically generate an ERROR on first attempt on RK3588.
# Rescan using MMC legacy mode
=> mmc rescan 0
# Write a single block to sector 0x4000 fails with ERROR
=> mmc write 20000000 4000 1
# Write a single block to sector 0x4000 now works
=> mmc write 20000000 4000 1
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.
