Since RZ/A1 (R7S72100) does not support HS mode, remove it from the
host caps.

Doesn't HS mode? Then it's only supported the legacy mode?

Sorry, please ignore this patch.
The MMC controller in the RZ/A1 can generate up to a 33MHz clock, so it
does support "High Speed" mode.
I just tested it and it works fine the way it is.
