[PATCH] mmc: sdhci: Setup HS modes based on HISPD bit

[Michal Simek]

There is no reason to setup HS modes by default without checking bit in
capability register.
Setting up HS mode by default breaks option to disable HS mode via
sdhci-caps-mask DT property.

Disabling HS mode can be done via DT as:
sdhci-caps-mask = <0 0x200000>;
