drivers/firmware: Don't mark as busy the simple-framebuffer IO resource

The sysfb_create_simplefb() function requests a IO memory resource for the
simple-framebuffer platform device, but it also marks it as busy which can
lead to drivers requesting the same memory resource to fail.

Let's drop the IORESOURCE_BUSY flag and let drivers to request it as busy
instead.
