hwmon: (occ) Rework attribute registration for stack usage
clang produces an output with excessive stack usage when building the
occ_setup_sensor_attrs() function, apparently the result of having
a lot of struct literals and building with the -fno-strict-overflow
option that leads clang to skip some optimization in case the 'attr'
pointer overruns:
drivers/hwmon/occ/common.c:775:12: error: stack frame size (1392) exceeds limit (1280) in 'occ_setup_sensor_attrs' [-Werror,-Wframe-larger-than]
Replace the custom macros for initializing the attributes with a
simpler function call that does not run into this corner case.
