[PATCH 1/2] mmc: fsl_esdhc_imx: fix the mask for tuning start point

[haibo.chen at nxp.com]

From: Haibo Chen <haibo.chen at nxp.com>

According the RM, the bit[6~0] of register ESDHC_TUNING_CTRL is
TUNING_START_TAP, bit[7] of this register is to disable the command
CRC check for standard tuning. So fix it here.

Fixes: fa33d207494c ("mmc: split fsl_esdhc driver for i.MX")
