cbfstool locate: Rename -a align switch to -P for page size

Browse Source 
cbfstool usage change:
   The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".

The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
  cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
  # output: 0x44, which does not look like aligned to 0x40000.

To prevent confusion, it's now switched to "-P/--page-size".

Verified by building i386/axus/tc320 (with page limitation 0x40000):
 cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
 # output: 0x44
