Re: [U-Boot] [PATCH v2 2/3] sunxi-mmc: don't double clock for new mode unconditionally

Comment in Linux driver says that clock needs to be doubled only if we use DDR modes, moreover divider has to be set accordingly.

U-boot driver doesn't declare support for any DDR modes and doesn't set internal clock divider in CLKCR, so it doubles clock unconditionally when new mode is used.

Some cards can't handle that and as result SPL fails to load u-boot.
