nicintel_eeprom: Support for I210 emulated EEprom
On the I210 family there is no MAC EEprom, instead there is a big flash
(typically around 16Mb) with contents of the old MAC plus other stuff.
There is an interface to program the whole flash, but once it is
programmed it enters a "Secure Mode" that disables the interface.
Luckily, the section with the MAC can still be updated via the EEprom
interface. This patch adds support for this interface.
