[PATCH] regmap: permit to set reg_update_bits with bulk implementation

[Christian Marangi <ansuelsmth@gmail.com>]

A regmap may still require to set a custom reg_update_bits instead of
relying to the regmap_bus_read/write general function.

Permit to set it in the map if provided by the regmap config.

If this is accepted, this is needed for net-next tree so a signed tags
is needed, if it's not a problem.
