The reset value of "uSDHCx_INT_STATUS_EN" register is changed to 0 on iMX6SX. So the fsl_esdhc driver must update to set the register, otherwise no state can be detected.

Signed-off-by: Ye.Li B37916@freescale.com --- Changes since v2: - None

Changes since v1: - Remove codes which set INT_STATUS_EN register according PIO or DMA mode.
