No need to set provider on AMD DRI3 config

[Danny Hsu]

For I+A config, we added test case for AMD offloading before, but that was for AMD DRI2 driver, the driver was changed to DRI3 on current platforms, there is no need to set provider anymore.

* AMD GPU Test (I+A) (DRI2)
  $ xrandr --listproviders
  $ xrandr --setprovideroffloadsink provider (DIS) sink (UMA)
  $ DRI_PRIME=1 glxgears

* AMD GPU Test (I+A) (DRI3)
  * xrandr commands are not necessary, just run the following command to do test.
  $ DRI_PRIME=1 glxgears

Base on https://wiki.archlinux.org/index.php/PRIME, there is a note describing as following

Note: This setting (xrandr --setprovideroffloadsink provider sink) is no longer necessary when using the default intel/modesetting driver from the official repos, as they have DRI3 enabled by default and will therefore automatically make these assignments.
