Replace device_get_match_data() and i2c_match_id() by i2c_get_match
_data() by making similar I2C and DT-based matching table.

Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

v2->v3:
 * Added .name field to MCP4531_ID_TABLE macro
 * Replaced MCP4531_ID_TABLE(name, cfg)->MCP4531_ID_TABLE(_name, cfg)
v1->v2:
 * Added similar similar I2C and DT-based matching table.
 * Fixed typo i2c_get_match_data(dev)->i2c_get_match_data(client).
 * Dropped error check as all tables have data pointers.

Note:
 This patch is only compile tested.

Applied.

Whilst I think these are good in general, I don't particularly want to
see blanket conversions of drivers that do it differently (unless they
are buggy ;)  I don't mind such stuff that I'd consider a small cleanup
but it does take review time so I'll push them behind other series with
a greater benefit.

Thanks,

Jonathan
