[Intel-gfx] [CI] drm/i915/gt: Apply the magic PM interval roundup to all!

[kbuild test robot]

Hi Chris,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on drm-intel/for-linux-next]
[also build test WARNING on drm-tip/drm-tip]
[cannot apply to v5.7-rc3 next-20200424]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
