gpu: nvgpu: remove NVGPU_GR_NUM_INSTANCES

Browse Source 
common.gr defined a temporary macro NVGPU_GR_NUM_INSTANCES to enable or
disable multiple GR instances from common.gr unit.
Multiple GR instance boot is now verified, so we can remove this
temporary solution.

Note that nvgpu_grmgr_get_num_gr_instances() will return more than 1
instance only if NVGPU_SUPPORT_MIG is enabled.

Update unit tests to set number of syspipes to 1 to allow enumeration
of GR instance by grmgr.

Jira NVGPU-5648
