ae2a1e7dfc tegra: hwpm: redraft regops ioctl return status 
- As regops ioctl status is an output from kernel, the status cannot be
invalid. So, remove TEGRA_SOC_HWPM_REG_OP_STATUS_INVALID define.
- Redefine regops ioctl status to make SUCCESS equivalent to value 0.
- Add TEGRA_SOC_HWPM_REG_OP_STATUS_WR_FAILED to indicate failure in
regops write command.
