Rename identifiers called 'byte'

Still fallout of adding "-Wshadow". Missed the ht1000 one
(chipset_enable is not compied on Windows where we had the collision
with "byte" last time) and the other occurrence is newly introduced.
Old libpci defines a global symbol called "byte" too.

Corresponding to flashrom svn r913.
