haswell: No need pre-graphics delay when in normal mode or resume from S3

When resume in normal, we won't use vgabios.bin. So no need this delay.
It can shorten the resume time ~300 ms to meet the criteria: resume < 1 second.

Per Stefan, the delay should not be enabled for resume from S3, only for
cold boot and only when in dev/recovery mode.

TEST=build & test_that IP f:.*power_Resume/control to check if
seconds_system_resume time < 1
