fel: add fel spl support for A83T

For A83T MMU is not enabled by BROM.
U-boot SPL support is not yet added for A83T.
tested using A33 u-boot binary.

$fel spl u-boot-sunxi-with-spl.bin
U-Boot SPL 2015.10-rc1-g1a8cf6d (Aug 17 2015 - 15:14:46)
DRAM:Timeout initialising DRAM.

it jumped to SPL and on serial it displayed above log from SPL.
I'll try to add U-boot SPL support for A83T soon.
