[U-Boot] [PATCH 1/3] mmc: ftsdc010: Support High-Speed mode

[Andes]

From: Rick Chen <rick at andestech.com>

ftsdc010 dm driver has been disable High-Speed mode
as default to work around Andes AE3XX platform's problem,
because of it does not support High-Speed mode in
commit id 73cd56b2df213c629191139e5c6705e069b6214f.

But other platforms or SoCs maybe support this function.
So High-Speed mode can be enabled from dts with
cap-mmc-highspeed or cap-sd-highspeed property.
