f8ea72d097 drm/amdkfd: Fix CP soft hang on APUs
The problem happens on Raven and Carrizo. The context save handler
should not clear the high bits of PC_HI before extracting the bits
of IB_STS.

The bug is not relevant to VEGA10 until we enable demand paging.

0db54b24ad drm/amdkfd: Separate trap handler assembly code and its hex values
Since the assembly code is inside "#if 0", it is ineffective. Despite that,
during debugging, we need to change the assembly code, extract it into
a separate file and compile the new file into hex values using sp3.
That process also requires us to remove "#if 0" and modify lines starting
with "#", so that sp3 can successfully compile the new file.

With this change, all the above chore is no longer needed, and
cwsr_trap_handler_gfx*.asm can be directly used by sp3 to generate its
hex values.
