dt-bindings: rtc: abx80x: Improve checks on trickle charger constraints 



The abracon,tc-diode and abracon,tc-resistor DT properties are only
valid for the ABx0804 and ABx0805. Furthermore, they must both be
present, or neither of them must be specified. Add rules to check this.

The generic abracon,abx08x compatible string doesn't indicate which chip
variant is used, but performs auto-detection at runtime. It must this
also allow the two above properties.
