drm/amdgpu/sdma: Remove superfluous rlc_resume and rlc_stop functions

Browse source

Every SDMA generation has an rlc_resume and rlc_stop function
which are not doing anything.

Starting from CIK, the SDMA engine supports additional queues
which are called "SDMA compute" or "RLC" queues, and these
queues are used by the KFD, and configured using the HWS.
There is nothing for the kernel driver to do for these.

Let's delete the functions that don't do anything.
In case of SDMA v4.0 and v4.4.2 let's move the init_pg()
call to the start() function.
