bcm63xx: 5.4: add removed helper syscon_regmap_lookup_by_pdevname
The helper syscon_regmap_lookup_by_pdevname has been removed in kernel patch
29d14b668d2f ("mfd: Remove unused helper syscon_regmap_lookup_by_pdevname")
due to lack of users.
However, we use this function in our local pinctrl drivers for BCM6358 and
BCM6368. Thus, we have to add it locally.
