flashrom: Support Pm49FL004/2 Block Locking Registers
The PMC chips understand both LPC and FWH flash commands. When in FWH mode (MSR_DIVIL_BALL_OPT(0x51400015) = 0x00000f7d on 5536 boards) the Block Locking Registers by default lock the flash chip for write and erase - in addition to any chipset write protection. This patch adds unlock operations before Pm49FL004/2 write and erase, and it includes an svn mv pm49fl004.c pm49fl00x.c Thanks go to Nikolay for this patch.
