[Patrick Rudolph (Code Review)]

Hello Aaron Durbin, Simon Glass, Stefan Reinauer, Paul Menzel, build bot (Jenkins), Martin Roth, Patrick Georgi,

em100: Detect emulated flash chip

It's not clear why uploads (EM100 to host) generate a 64MiB ROM file.
It turns out that the flash chip needs to be specified at the command line, which
isn't intentional.

Detect the currently emulated SPI and use the size as defined in flashchips.

Tested on EM100Pro, will now upload ROM files matching the currently emulated target
even without specifying the flash chip on the command line.
