ifdtool: Add option to specify platform (-p) quirks
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 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.
