CHROMIUM: fix and refine RO FMAP sections
To update firmware, GBB must be aligned to 4K, and FMAP should be
best aligned to as large as possible. Dummy "RECOVERY" section should
better also exist (even with zero size).
We also realized that FMAP section size should be increased to hold
current firmware image sections because current size (1k) cannot hold
all existing sections. 4K is a better size.
This CL tries to refine section location and size so that both GBB and
FMAP are aligned to >=4K location.
BUG=chromium-os:17646
TEST=build_packages; dump_fmap /build/tegra2_aebl/u-boot/image.bin
# seeing no errors, image size=4M, FMAP section=4K,
# GBB offset aligned to 4K
