Various IT85* cleanups and fixes

Browse Source 
Fix a few typos.
Change the EC memory region mapping name.
Drop unused function parameter.
Use mmio_writeb()/mmio_readb() to get reliable access to volatile memory
locations instead of plain pointer access which is optimized away by gcc.
Use own it85_* SPI high-level chip read/write functions instead of
relying on unrelated ICH functions.

Corresponding to flashrom svn r1279.

I applied the patch against the Chromium OS branch and
successfully tested read and write operations on a Cr48.
