exynos: Fix it so that we overwrite any existing rev map if it's there
Without this change the SD-card flasher on exynos5420 did not work
(though the USB flasher did). What was happening:
1. We'd create the original U-Boot OK and bundle it.
2. We'd extract the BL1/BL2 out of the created U-Boot image. The BL2
size would be read out of the flashmap as 32K.
3. We'd re-bundle the BL2 and re-add a revision map at the end
4. The variable-size SPL code didn't appear to work right with a BL2
that was > 32K when booting from SD card.
Change is so that if we find an existing revision map we replace it.
BUG=None
TEST=Flasher image flashed to SD card works.
