[flashrom] [PATCH]Updated patch to use flashrom on libpayload

[Patrick Georgi]

Hi,

attached patch is updated to current trunk, with some minor cleanup in
the MSR routines (no need to explicitely cast to unsigned long long).

With this patch, it's easier to build flashrom with libpayload, but some
crucial parts are still missing, most notably the frontend.
Once flashrom is a library, it will be relatively easy to use.
