realtek: fix/add switchcore syscon nodes for RTL838x/RTL839x/RTL931x

The switchcore node is the central location that describes the Realtek switch
register addresses starting at 0x1b000000. It will be used by current and
future regmap enabled device drivers. The upstream MDIO driver already makes
use of it by calling syscon_node_to_regmap(dev->parent->of_node);

In the current DTS base we have 3 issues that should be fixed:

- rtl838x.dtsi has a length of 0x20000 instead of 0x10000
- rtl839x.dtsi has a length of 0x20000 instead of 0x10000
- rtl931x.dtsi has no switchcore node at all

Align these mismatches with the "good" RTL930x template.
