SPI: Fix Eon support

The Eon SPI25 code had a number of issues:
 - fix page write calculation
 - fix erase segment
 - fix id check
 - fix sector size
 - make commands EN25 generic
This makes the code similar to other SPI25 devices used in coreboot.

BUG=chrome-os-partner:25907
BRANCH=baytrail(rambi)
TEST=Read and write MRC and ELOG on Glimmer with Eon device.
