flashrom: bump to 1.2

Add new PCI and USB drivers to flashrom.mk to disable them in other
build variant.s
Fix DefineConfig calls to use new config symbols, and have it only
append NEED_FEATURE=yes to MAKE_FLAGS. Appending NEED_FEATURE=no would
still enable the feature because upstream compares against an empty
string instead of comparing to yes.
Drop libusb-compat dependency as all drivers use libusb-1 now.
Remove upstreamed patch 010-add-arc.patch.
Rework 0001-fix_internal_bitbang.patch, give it a correct prefix and
more descriptive name.
