Subject: [PATCH 0/3] Use DELAY_ENABLE macro for RK3328, RK3566/RK3568 and RK3588

Almost all Rockchip GMAC variants use the DELAY_ENABLE macro to help
enable or disable use of MAC rx/tx delay. However, RK3328, RK3566/RK3568
and RK3588 GMAC driver does not.

Use of the DELAY_ENABLE macro help ensure the MAC rx/tx delay is
disabled, instead of being enabled and using a zero delay, when
RGMII_ID/RXID/TXID is used.

RK3328 driver was merged around the same time as when DELAY_ENABLE was
introduced so it is understandable why it was missed. Both RK3566/RK3568
and RK3588 support were introduced much later yet they also missed using
the DELAY_ENABLE macro (so did vendor kernel at that time).

This series fixes all these cases to unify how GMAC delay feature is
enabled or disabled across the different GMAC variants.
