main/postmarketos-initramfs: get to splash faster (MR 4204)

With full-fat mdev supporting by-partlabel lookups, there is a small
delay during startup. As mdev and dynamic partitions aren't actually
needed for the framebuffer device, move show_splash earlier.

Furthermore, slightly rework setup_framebuffer to not dump the verbose
message about waiting for the framebuffer unless the framebuffer isn't
found.
