Update flashrom - in particular, this includes support for new chipsets
like Jasper Lake.
CONFIG_INTERAL_X86 was created so CONFIG_INTERNAL could apply to other
platforms, enable it for x86.
The default build target now requires sphinx, just build flashrom
itself.
Update flashrom_progress - filter out noise in newer flashrom that
chokes the progress bar implementation, make size detection more
robust, improve progress bar implementation slightly.
