Zhi Li c2e152f7ce net: stmmac: eswin: validate RGMII delay values 
Validate rx-internal-delay-ps and tx-internal-delay-ps against the
hardware capabilities of the EIC7700 MAC.

The programmable RGMII delay supports 20 ps steps and a maximum value of
2540 ps. The driver previously accepted arbitrary values and silently
truncated unsupported settings when converting them to hardware units.

As a result, invalid device tree values could lead to unexpected delay
programming and incorrect RGMII timing.

Reject delay values that are not multiples of 20 ps or exceed the
supported hardware range.

Fixes: ea77dbbdbc ("net: stmmac: add Eswin EIC7700 glue driver")
