Change in flashrom[staging]: Enable continuous SPI reads

[Urja Rannikko (Code Review)]

Hello Stefan Tauner, David Hendricks, Paul Menzel, build bot (Jenkins), Nico Huber,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/20223

to look at the new patch set (#4).

Change subject: Enable continuous SPI reads
......................................................................

Enable continuous SPI reads

Previous unnecessary page-by-page reading is repurposed to
read by big naturally aligned areas (now chip size limited
to 16MB for future-proofing of 4 byte addressed multi-die chips)
and serprog hack for continuous reads is removed.
