pmbootstrap installs unneeded firmware to device

Created by: sicelo

I notice that pmbootstrap install installs a lot of firmware that will not get used on the device. My target is Nokia-N900 and in the log I see installation of linux-firmware-i915, linux-firmware-ath9k, linux-firmware-amdgpu, among others, and a whole of other linux-firmware-* packages.

I think this behavior could be changed. I understand that sometimes we may want to use that firmware if, for example, we connect a device via USB host, but in general I doubt this firmware is needed on most devices, at least for sure on N900.
