iio: adc: max11410: make vref register name arrays static const

The vrefp_regs and vrefn_regs arrays are constant lookup tables and
are not modified.

Make them static const so they are not reinitialized on each probe
call and are placed in read-only memory. Mark the pointer array as
const as well to prevent unintended modification.
