[PATCH] arm64: dts: rockchip: fix eMMC corruption on NanoPC-T6 with A3A444 chips

[Tianling Shen]

From: Grzegorz Sterniczuk <grzegorz at sternicz.uk>

Some NanoPC-T6 boards with A3A444 eMMC chips experience I/O errors and
corruption when using HS400 mode. Downgrade to HS200 mode to ensure
stable operation.
