sunxi: mmc: add support for Allwinner A523 MMC mod clock

The Allwinner A523 SoC has a slightly changed mod clock, where the P
factor, formerly a shift value, is now a second divider value.
Also the input clock is not PLL_PERIPH0 (600MHz) anymore, but
PLL_PERIPH0_400M (for MMC0/1), so adjust the input rate calculation
accordingly. MMC2 has a different set of parents, so the input clock
is 800 MHz there.
Adjust for all of this.
