Don't populate the arrays on the stack, instead make them static.
Makes the object code smaller by over 950 bytes:

Before:
   text    data     bss     dec     hex filename
  26144   18768     352   45264    b0d0 drivers/hwmon/asc7621.o

After:
   text    data     bss     dec     hex filename
  25029   18928     352   44309    ad15 drivers/hwmon/asc7621.o
