mfd: twl4030-power: Fix regression with missing compatible flag

Commit e7cd1d1eb16f ("mfd: twl4030-power: Add generic reset
configuration") accidentally removed the compatible flag for
"ti,twl4030-power" that should be there as documented in the
binding.

If "ti,twl4030-power" only the poweroff configuration is done
by the driver.
