sculpt_manager: start fb on second CPU on Pocket

Browse Source 
With this commit the fb driver is started on the second CPU on the
MNT Pocket Reform to decouple it from the other components started
on the first CPU during the system's boot-up and mitigates bring-up
issues with this driver that result in an often non-working display.

Issue #5378.
