soc/intel/alderlake: Preserve eSOL for late CSE sync

This patch prevents the eSOL screen from being wiped out on Alder Lake
platforms that use late CSE sync (from ramstage). This allows the eSOL
text message to remain visible until ramstage.

Currently, the eSOL only functions during the early boot phase (until
romstage), so platforms like Nissa/Nirul and Trulo, which use CSE sync
from ramstage, cannot display any eSOL messages to the user.

A future patch will ensure the eSOL remains relevant for CSE sync in
ramstage, but this patch is necessary to avoid tearing down the IGD text
mode when exiting romstage.

BUG=b:359814797
TEST=eSOL text mode is not torn down when exiting romstage.
