[coreboot-gerrit] Change in em100[master]: Make firmware update hardware version aware

[Stefan Reinauer (Code Review)]

Hello build bot (Jenkins), Patrick Georgi, Furquan Shaikh, Martin Roth,

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

to look at the new patch set (#2).

Change subject: Make firmware update hardware version aware
......................................................................

Make firmware update hardware version aware

Up to now, you can accidently write an EM100Pro firmware version on
an EM100Pro-G2 device. This will brick your device and can not easily
be recovered with a SPI flasher, so be careful.
Hence, the firmware update code should make sure that HW version 4 is
used to commence a firmware update.

Right now, release binaries do not contain EM100Pro-G2 firmware images,
so this version of the code bails out on anything but HW version 4.
