[U-Boot] BIOS EMULATOR driver

[Viktor Křivák]

Hello,
I'm working on one project about bios emulator and I notice that this
driver is linked for boards P1022DS and sequoia too, but they don't really
use any methods of it. It's safe to remove this support from configs files?
Whole this driver is seems to be imported from somewhere and lots of its
code is unused Actually only one method is used. It's safe to clean this
too?

Thanks for answer
