efi: sysfb_efi: Fix DMI quirks not working for simpledrm
Commit 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") moved the sysfb_apply_efi_quirks() call in sysfb_init()
from before the [sysfb_]parse_mode() call to after it.
But sysfb_apply_efi_quirks() modifies the global screen_info struct which
[sysfb_]parse_mode() parses, so doing it later is too late.
This has broken all DMI based quirks for correcting wrong firmware efifb
settings when simpledrm is used.
To fix this move the sysfb_apply_efi_quirks() call back to its old place
and split the new setup of the efifb_fwnode (which requires
the platform_device) into its own function and call that at
the place of the moved sysfb_apply_efi_quirks(pd) calls.
Fixes: 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup for all arches")
