This series is originally based out of [1], and built on top of [2].

The primary departure from [1] was that vbt is no longer cached. During vbt
show, based on the source of vbt, it would simply be re-read reducing the
read/cleanup complexity. With this series debugfs dump of vbt should work on
all the platforms that support display.

v3 of the series extracts opregion firmware check and harmonizes the memory
handling of different variants viz. opregion/oprom/spi/fimrware
