[coreboot] setting ipxe rom path deslects ipxe option

[Martin Roth]

Hi Andrew,
  I was able to reproduce this issue.  It looks like the 'optional'
keyword is creating some odd behavior.  Thanks for letting us know.

Here's the patch to fix the problem.

Because of the way the Kconfig was rewritten, you'll have to re-enable
it after applying the patch, but it should fix the issue going
forward.
