mmc: core: Fix voltage select in DDR mode
commit 913047e9e5787a90696533a9f109552b7694ecc9 upstream.
This patch fixes the wrong comparison before setting the interface
voltage in DDR mode.
The assignment to the variable ddr before comaprison is either
ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison
is done with the extended csd value if ddr == EXT_CSD_CARD_TYPE_DDR_1_2V.
