ARM: OMAP: Fixed OMAP1510 SRAM size again

According to spru602b.pdf TRM, 1510 has 192K of SRAM, not 512K

  * The amount of SRAM depends on the core type:

  * Note that we cannot try to test for SRAM here because writes
  * to secure SRAM will hang the system. Also the SRAM is not
  * yet mapped at this point.
