cbfstool locate: Implement alignment switch --align/-a
cbfstool usage change:
"-a" for "cbfstool locate" can specify base address alignment.
To support putting a blob in aligned location (ex, microcode needs to be aligned
in 0x10), alignment (-a) is implemented into "locate" command.
Verified by manually testing a file (324 bytes) with alignment=0x10:
cbfstool coreboot.rom locate -f test -n test -a 0x10
# output: 0x71fdd0
cbfstool coreboot.rom add -f test -n test -t raw -b 0x71fdd0
cbfstool coreboot.rom print -v -v
# output: test 0x71fd80 raw 324
# output: cbfs_file=0x71fd80, offset=0x50, content_address=0x71fdd0+0x144
Also verified to be compatible with old behavior by building i386/axus/tc320
(with page limitation 0x40000):
cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
# output: 0x44
cbfstool coreboot.rom locate -f x.bin -n romstage -P 0x40000 -a 0x30
# output: 0x60
