mmc: mediatek: Fixed bug where clock frequency could be set wrong
[ Upstream commit 40ceda09c8c84694c2ca6b00bcc6dc71e8e62d96 ]
This patch can fix two issues:
Issue 1:
In previous code, div may be overflow when setting clock frequency
as f_min. We can use DIV_ROUND_UP to fix this boundary related
issue.
Issue 2:
In previous code, we can not set the correct clock frequency when
div equals 0xff.
