regmap: add helper macro to set min/max range of register
Add helper macro to set the min and max value of the register range.
This is useful when initialising the register ranges of the device like
static const struct regmap_range readable_ranges[] = {
regmap_reg_range(DEVICE_REG0, DEVICE_REG10),
};
