cbfstool: Update FIT entries in the second bootblock

Browse Source 
Once a second bootblock has been added using topswap (-j)
option, Update the entries in second FIT using -j option with
update-fit command.

Additionally add a -q option which allows to insert the address of
a FMAP region (which should hold a microcode) as the first entry in
the second FIT.

BUG=None
BRANCH=None
TEST= Create ROM images with -j options and update FIT using -q option.
example:
./build/util/cbfstool/cbfstool coreboot.tmp create \
	-M build/fmap.fmap -r COREBOOT,FW_MAIN_A,FW_MAIN_B,RW_LEGACY
build/util/cbfstool/cbfstool coreboot.tmp add \
	-f build/cbfs/fallback/bootblock.bin -n bootblock -t \
	bootblock -b -49152 -j 0x10000
build/util/cbfstool/cbfstool coreboot.tmp add-master-header -j 0x10000
build/util/cbfstool/cbfstool coreboot.tmp add -f build/cpu_microcode_blob.bin \
	-n cpu_microcode_blob.bin -t microcode -r COREBOOT -a 16
build/util/cbfstool/cbfstool coreboot.tmp. update-fit \
	-n cpu_microcode_blob.bin -x 4 -j 0x10000 -q FW_MAIN_A

Also try the failure scenarion by providing invalid topswap size.
