[0/1] devcoredump support for Panfrost GPU driver

Message

This patch adds support for devcoredump in the Panfrost driver. Code
structure is heavily inspired by similar functionality in the Etnaviv
driver, but the main goal of the crash dump is feeding it to a userspace
analyser that accesses the BO raw binary data to pass it to the pandecode
library.
