The DT binding says: - phy-reset-duration : Reset duration in milliseconds. Should present only if property "phy-reset-gpios" is available. Missing the property will have the duration be 1 millisecond. Numbers greater than 1000 are invalid and 1 millisecond will be used instead.
However the current code: - clamps values greater than 1000ms to 1000ms rather than 1. - does not initialize the delay if the property does not exist (else clause mismatch) - returns an error if phy-reset-gpios is not defined
Fix all this and simplify by using dev_read_u32_default()
