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.
