regulator: s5m8767: Bounds check id indexing into arrays

The compiler has no way to know if "id" is within the array bounds of
the regulators array. Add a check for this and a build-time check that
the regulators and reg_voltage_map arrays are sized the same. Seen with
GCC 13:

../drivers/regulator/s5m8767.c: In function 's5m8767_pmic_probe':
../drivers/regulator/s5m8767.c:936:35: warning: array subscript [0, 36] is outside array bounds of 'struct regulator_desc[37]' [-Warray-bounds=]
  936 |                         regulators[id].vsel_reg =
      |                         ~~~~~~~~~~^~~~
