[PATCH u-boot v2019.04-aspeed-openbmc v2 1/6] ast2600: Modify SPL SRAM layout

The SRAM is 89KB on the A1 and beyond:

 0x1000_0000 to 0x1000_ffff: 64KB, with parity check
 0x1001_0000 to 0x1001_5fff: 24KB, w/o parity check
 0x1001_6000 to 0x1001_63ff: 1KB, w/o parity check, each byte write once

Allow the image to fill the full 64KB payload size (max that secure boot
supports) and place the stack at the top of the 24KB of SRAM.
