Panthor is the open-source implementation for the Arm GPU Valhall series
both in the Linux kernel and Mesa userspace. In the latter, the panfrost
"driver" is actually handling this version of the Arm GPU. One therefore
needs to enable kmsro and panfrost in PACKAGECONFIG to be able to use
this open-source implementation.

The open-source implementation still requires a proprietary blob which
is running on the GPU: mali_csffw.bin. Note that the closed-source
implementation (libmali and vendor kernel drivers) also require this
blob.

In anticipation of the kmsro PACKAGECONFIG for gallium-drivers
disappearing soon[1], the latter commit removes the PACKAGECONFIG option
as well.
