The newly added a5xx support fails to build when debugfs is diabled:
drivers/gpu/drm/msm/adreno/a5xx_gpu.c:849:4: error: 'struct msm_gpu_funcs' has no member named 'show'
drivers/gpu/drm/msm/adreno/a5xx_gpu.c:849:11: error: 'a5xx_show' undeclared here (not in a function); did you mean 'a5xx_irq'?
This adds a missing #ifdef.
Fixes: b5f103ab98 ("drm/msm: gpu: Add A5XX target support")

Each of the per-generation callbacks was doing this. Lets just simplify
and move it into toplevel show() fxn.

This was never documented or used in upstream dtb. It is used by
downstream bindings from android device kernels. But the quirks are
a property of the gpu revision, and as such are redundant to be listed
separately in dt. Instead, move the quirks to the device table.

Most 5XX targets have GPMU (Graphics Power Management Unit) that
handles a lot of the heavy lifting for power management including
thermal and limits management and dynamic power collapse. While
the GPMU itself is optional, it is usually nessesary to hit
aggressive power targets.
The GPMU firmware needs to be loaded into the GPMU at init time via a
shared hardware block of registers. Using the GPU to write the microcode
is more efficient than using the CPU so at first load create an indirect
buffer that can be executed during subsequent initalization sequences.
After loading the GPMU gets initalized through a shared register
interface and then we mostly get out of its way and let it do
its thing.
