Arnd Bergmann 2c021b45c1 hwmon: (occ) fix unaligned accesses 
Passing a pointer to an unaligned integer as a function argument is
undefined behavior:

drivers/hwmon/occ/common.c:492:27: warning: taking address of packed member 'accumulator' of class or structure 'power_sensor_2' may result in an unaligned pointer value [-Waddress-of-packed-member]
  492 |   val = occ_get_powr_avg(&power->accumulator,
      |                           ^~~~~~~~~~~~~~~~~~
drivers/hwmon/occ/common.c:493:13: warning: taking address of packed member 'update_tag' of class or structure 'power_sensor_2' may result in an unaligned pointer value [-Waddress-of-packed-member]
  493 |            &power->update_tag);
      |             ^~~~~~~~~~~~~~~~~

Move the get_unaligned() calls out of the function and pass these
through argument registers instead.
