Add a flag to let drivers enable this behavior.

This becomes overhead when such use cases are high. Having a common function to do this is much convenient and less error prone. The idea of regmap_field is simple, regmap_field gives a logical structure to bits of the regmap register, and the driver can use this logical entity without the knowledge of the bit positions and masks all over the code. This way code looks much neat and it need not handle the masks, shifts every time it access the those entities. With this new regmap_field_read/write apis the end user can setup a regmap field using regmap_field_init and use the return regmap_field to read write the register field without worrying about the masks or shifts. Also this apis will be useful for drivers which are based on regmaps, like some clocks or pinctrls which can work on the regmap_fields directly without having to worry about bit positions.
