[PATCH] sunxi: add fdtoverlay_addr_r environment variable
Commit 69076dff2284 ("cmd: pxe: add support for FDT overlays") added support for loading DT overlay files to PXE boot. However, it needs additional environment variable which points to memory location which can be used to temporary store overlay data.
Add it and in the process unify alignment using spaces.

Thanks, looks good. Briefly tested with manually applying a simple overlay, loaded to that address. Checked that the other addresses don't change.
One nit below, with that:

This is no longer true. ^^^^^^^^ But there is no such requirement, so we can just remove this line.
Cheers, Andre
