/**
* Test specification for: test_pbdma_status
*
* Description: Branch coverage for nvgpu_pbdma_status_* functions.
*
* Test Type: Feature based
*
* Input: test_fifo_init_support() run for this GPU.
*
* Steps:
* - Build fake struct nvgpu_pbdma_status_info.
* - Check that nvgpu_pbdma_status_is_chsw_switch is true when
* chsw status is NVGPU_PBDMA_CHSW_STATUS_SWITCH, false otherwise.
* - Check that nvgpu_pbdma_status_is_chsw_load is true when
* chsw status is NVGPU_PBDMA_CHSW_STATUS_LOAD, false otherwise.
* - Check that nvgpu_pbdma_status_is_chsw_save is true when
* chsw status is NVGPU_PBDMA_CHSW_STATUS_SAVE, false otherwise.
* - Check that nvgpu_pbdma_status_is_chsw_valid is true when
* id_type is PBDMA_STATUS_ID_TYPE_TSGID, false otherwise.
* - Check that nvgpu_pbdma_status_is_next_id_type_tsg is true when
* next_id_type is PBDMA_STATUS_NEXT_ID_TYPE_TSGID, false otherwise.
*
* Output: Returns PASS if all branches gave expected results. FAIL otherwise.
