arm: spear: Fix booting - relocate vector table to 0 (low-vector)

Booting SPEAr600 eval board doesn't work with current mainline U-Boot. With
this patch the low-vector bit is left to '0'. Resulting in the common
relocation of the vectors to 0 (SDRAM) to work correctly.

Tested on the SPEAr600 EVB.
