Zhen Chen fb91362a23 MALI: valhall: upgrade DDK to g29p0-00eac0, from g28p0-00eac0 
mali_csffw.bin from Valhall DDK g29(r54) is included.

In addition, in kbase_device_runtime_suspend(), some lines of codes added by r54 was removed.
If these lines of code are executed together with
"the code for powering off the GPU with a delay on the RK platform",
it will lead to a deadlock.
