[U-Boot] [PATCH] sunxi: Tweak various memory addresses

[Hans de Goede]

For the upcoming nand support we need a bigger heap, esp. ubi[fs] uses
quite a bit of memory, increase the heap size to 64 MB.

Our video code returns unused reserved framebuffer memory to the kernel
before booting it. Drop the #ifdef-ery and simply always reserve 16 MB.

Adjust bootm_size for the above changes.
