soc/intel/broadwell: Conditionally skip PRE_GRAPHICS_DELAY
It was commented that the need for the delay was mainly related
to external displays and only with VBIOS execution. Move the
delay such that it is done only when we actually need to execute
the VBIOS aka option rom.
A delay is currently only defined for librem/purism_bdw in
its Kconfig. As the description of the issue sounds like it
would equally happen on other platforms when VBIOS is involved,
promote the Kconfig visible option to global scope.
