[U-Boot] [PATCH v2 1/3] sunxi-mmc: introduce new MMC_SUNXI_HAS_MODE_SWITCH option

[Vasily Khoruzhick]

A64 doesn't have a mode switch in CCM, and CCM_MMC_CTRL_MODE_SEL_NEW
is not defined, so compilation fails if MMC_SUNXI_HAS_NEW_MODE is enabled

Introduce new MMC_SUNXI_HAS_MODE_SWITCH option to be able to ifdef usage
of CCM_MMC_CTRL_MODE_SEL_NEW
