[PATCH v2 26/47] power/reset: msm-poweroff: Register with kernel poweroff handler

[Guenter Roeck]

Register with kernel poweroff handler instead of setting pm_power_off
directly. Select fallback priority since the code does not really poweroff
the system but resets it instead.

Signed-off-by: Guenter Roeck <linux@xxxxxxxxxxxx>

v2:
- Use define to specify poweroff handler priority
- Fix headline and description
- Merge with restart handler code now used in same driver
- Use dev_warn instead of dev_err
