ARM: OMAP3_LOGIC: Fix SPL Memory Map for Falcon Mode

The memory map defined in commit ("49c7303f0e52: OMAP3: Enable SPL
on omap3_logic) was used by a copy-paste of another board without
fully understanding how the map works in Falcon mode.  This patch
undoes the customization and uses the default SPL Memory Map
for OMAP3.

When building the uImage, set LOADADDR=0x82000000 and Falcon
mode should properly load.
