efifb: Show framebuffer layout as device attributes
Userland sometimes needs to know what the framebuffer configuration was when the firmware was running. This enables us to render localized status strings during firmware updates using the data from the ACPI BGRT table and the protocol described at the url below: https://msdn.microsoft.com/en-us/windows/hardware/drivers/bringup/boot-screen-components This patch also fixes up efifb's printk() usage to use pr_warn() / pr_info() / pr_err() instead.
