regmap: Wire up regmap_config provided bulk write in missed functions

There are some functions that were missed by commit d77e7456 ("regmap:
Add bulk read/write callbacks into regmap_config") when support to define
bulk read/write callbacks in regmap_config was introduced.

The regmap_bulk_write() and regmap_noinc_write() functions weren't changed
to use the added map->write instead of the map->bus->write handler.

Also, the regmap_can_raw_write() was not modified to take map->write into
account. So will only return true if a bus with a .write callback is set.
