regulator: qcom_spmi: Constify struct spmi_voltage_range
'struct spmi_voltage_range' are only modified at runtime to compile a
field, n_voltages, that could be computed at compile time.
So, simplify spmi_calculate_num_voltages() and compute n_voltages at
compile time within the SPMI_VOLTAGE_RANGE macro.
Constifying these structures moves some data to a read-only section, so
increase overall security.
