Almost all of the newer Allwinner SoCs have a new operating mode for the eMMC clocks that needs to be enabled in both the clock and the MMC controller.

Details about that mode are sparse, and the name itself (new mode vs old mode) doesn't give much details, but it seems that the it changes the sampling of the MMC clock. One side effect is also that it divides the parent clock rate by 2.

Add support for it through a Kconfig option.
