[U-Boot] [PATCH] arm: socfpga: fix CONFIG_SPL_MAX_SIZE (less than SRAM)

[Simon Goldschmidt]

The boot ROMs of the socfpga platform limit the size of the
SPL to copy to less than the available SRAM.
(See "Intel SoC FPGA Embedded Development Suite User Guide")

According to this document, Cyclone V and Arria V allow 60KB
maximum while Arria 10 allows 200KB. In both cases, this is
less than CONFIG_SYS_INIT_RAM_SIZE.
