drm/imagination: Remove firmware enable_reg
After a previous commit ("drm/imagination: Mask GPU IRQs in threaded
handler"), this register is now only used to enable firmware interrupts at
start-of-day. This is, however, unnecessary since they are enabled by
default.
In addition, the soon-to-be-added RISC-V firmware processors do not have
an equivalent register.
