Revert "mmc: sdhci: Fix incorrect switch to HS mode"

commit 07bcc411567cb96f9d1fc84fff8d387118a2920d upstream.

This reverts commit c894e33ddc1910e14d6f2a2016f60ab613fd8b37.

This commit aims to treat SD High speed and SDR25 as the same while
setting UHS Timings in HOST_CONTROL2 which leads to failures with some
SD cards in AM65x. Revert this commit.

The issue this commit was trying to fix can be implemented in a platform
specific callback instead of common sdhci code.
