Add a Kconfig option which users can select when they want to boot older kernels, e.g. the linux-sunxi 3.4 kernels. For now this just forces the pll5 "p" value to 1 (divide by 2) as that is what those kernels are hardcoded too, in the future this may enable further workarounds.

sunxi builds always enable mmc0, some boards also have a second sdcard

slot or emmc on mmc1 - mmc3. Setting this to 1, 2 or 3 will enable

support for this.
