Apollo Lake uses yet another descriptor format where only two masters
are used: CPU/BIOS and CSE/TXE. CSE stores data in a region number 5
that has not been used previously and CPU must not write it. Add quirk
(-p aplk) that locks descriptor according to recommended values.
BUG=chrome-os-partner:58974
BRANCH=None
TEST=ifdtool -p aplk -l bios.bin; ifdtool -d bios.bin.new. Make sure
FLMSTR1 and FLMSTR2 are set correctly. unlock with -l and make sure
FLMSTRs are restored.
