[U-Boot] [PATCH] arm: socfpga: check total size of SPL

[Simon Goldschmidt]

Correctly define CONFIG_SPL_MAX_FOOTPRINT to make the default arm
linker script for SPL check the total SRAM size available for SPL
(code, data, bss, heap, global data).

The previously existing define CONFIG_SPL_MAX_SIZE seems to only
check the binary size (which is without bss, heap and gd).
