sunxi: introduce extra config option for boot0 header

Browse Source 
The ENABLE_ARM_SOC_BOOT0_HOOK option is a generic option shared with
other boards. To allow alternative code to be inserted, we create
another, now function specific config symbol on top of it to simplify
later additions. No functional change at this time.

Prepend a 1536 byte (empty) header to the U-Boot image file, to be
filled with magic values post build. The Allwinner provided boot0
blob relies on this information to load and execute U-Boot.
Only needed on 64-bit Allwinner boards so far when using boot0.
