Revert "drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync"
This reverts commit 60aebc9559492cea6a9625f514a8041717e3a2e4. Commit 60aebc9559492cea ("drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync") messes up initialization order of the graphics drivers and leads to blank displays on some systems. So revert the commit. To make the display drivers fully independent from initialization order requires to track framebuffer memory by device and independently from the loaded drivers. The kernel currently lacks the infrastructure to do so.
