sunxi: Skip MMC0 init when its pinmux conflicts with UART0
Currently, selecting UART0_PORT_F entirely disables MMC support on sunxi platforms. But this is a bigger hammer then needed. Muxing UART0 to the pins on port F only causes a conflict with MMC0, so minimize the impact by specifically skipping MMC0 init. We can continue to use MMC1/2 if those are enabled. Let's also remove the preprocessor check while refacting this function.
