PM-QA update

Hi all, PM-QA is updated:

1. Removed obsolete test cases under pm-qa/tastcases

2. Thermal test scripts has been merged into, but is temporarily disabled form the top 'make check', while ‘make -C thermal check’ still works for this sub-test.

3. Temporarily disabled suspend function form top 'make check', this will be enabled after fully test on LEBs later, also 'make -C suspend check' is available.

Any problems you found please let me know, thanks.
