Prepare a single regmap covering the entire SPI address space of the

This regmap is address-zero-based (can access the entire switch address
space) and child devices are supposed to access their respective memory
region with the help of struct resource (IORESOURCE_REG, to be precise).

Nothing is currently done with the regmap, it is just allocated and
added to the device's devres list, so it doesn't need to be freed.

It looks to me that somebody missed grouping above (not this change) and it's
better to have it done:

#include <linux/dsa/8021q.h>
#include <linux/mutex.h>
#include <linux/regmap.h>

#include <net/dsa.h>

#include "sja1105_static_config.h"

Hmm... Perhaps return dev_err_probe(...); ?
