pinebookpro-firmware: update to 0.0.20220515, fix dead links.

This is firmware for broadcom 43456

It's unclear if this firmware is needed at all.

linux-firmware has broadcom 43455 with patchset for pinebookpro

Manajro has license as "unknown".

The linux-firmware mailing suggests that the firmware hasn't been
upstreamed due to licensing issues:

Should void be distributing this at all?
