fsl_esdhc: Deal with watermark level register related changes
P1010 and P1014 has v2.3 version of FSL eSDHC controller in which watermark
level register description has been changed:
9-15 bits represent WR_WML[0:6], Max value = 128 represented by 0x00
25-31 bits represent RD_WML[0:6], Max value = 128 represented by 0x00
