Christian Hewitt 2bd02f5a0b drm/panfrost: fix power transition timeout warnings ...

Increase the timeout value to prevent system logs on Amlogic boards flooding
with power transition warnings:

[   13.047638] panfrost ffe40000.gpu: shader power transition timeout
[   13.048674] panfrost ffe40000.gpu: l2 power transition timeout
[   13.937324] panfrost ffe40000.gpu: shader power transition timeout
[   13.938351] panfrost ffe40000.gpu: l2 power transition timeout
...
[39829.506904] panfrost ffe40000.gpu: shader power transition timeout
[39829.507938] panfrost ffe40000.gpu: l2 power transition timeout
[39949.508369] panfrost ffe40000.gpu: shader power transition timeout
[39949.509405] panfrost ffe40000.gpu: l2 power transition timeout

The 2000 value has been found through trial and error testing with devices
using G52 and G31 GPUs.
