[PATCH V2 1/5] regmap: add helper macro to set min/max range of register

[Laxman Dewangan <ldewangan@nvidia.com>]

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),
};

As per Mark's comment on V1 series, adding the macro in header in place
of defining in driver.
This should go on same tree as 2/5.
