net: dsa: microchip: Factor out regmap config generation into common header
The regmap config tables are rather similar for various generations of the KSZ8xxx/KSZ9xxx switches. Introduce a macro which allows generating those tables without duplication. Note that $regalign parameter is not used right now, but will be used in KSZ87xx series switches.
