gpu: nvgpu: remove use of linux specific powergate_mode flag

In dbg_set_powergate(), we use flags NVGPU_DBG_GPU_POWERGATE_MODE_DISABLE/ENABLE
which are defined in linux specific uapi header
Hence we need to remove those flags from common code

Update dbg_set_powergate() to receive boolean flag to disable/enable powergate
instead of NVGPU_DBG_GPU_POWERGATE_MODE_DISABLE/ENABLE

Also update corresponding HALs as per above change

Jira NVGPU-259
