regmap: Wire up regmap_config provided bulk write in missed functions
There are some functions that were missed by commit d77e74561368 ("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.
Fixes: d77e74561368 ("regmap: Add bulk read/write callbacks into regmap_config")
