Embed Mali GPU firmware via CONFIG_EXTRA_FIRMWARE, disable CONFIG_DRM_PANFROST

Browse source 
Panthor (Mali-G610 driver) requests mali_csffw.bin at ~1.2s, before /vendor
mounts at ~2.4s. With FW_LOADER_USER_HELPER intentionally disabled, the
firmware request fails instantly and probe fails. Embed the 276KB blob
directly in the kernel Image so firmware is always available at probe time.

Also disable CONFIG_DRM_PANFROST (Midgard/Bifrost driver) — it will never
bind a Valhall G610 GPU and is dead weight alongside panthor.
