[BISECTED, REGRESSION] Broken networking on MIPS/OCTEON EdgeRouter Lite

[Aaro Koskinen]

Hi,

When booting v5.1-rc1 on EdgeRouter Lite (MIPS/OCTEON), with at803x phy
driver enabled, networking no longer works - I even need to go physically
power cycle the board before getting networking to work again (otherwise
bootloader cannot tftp an older working image).

Bisected to:

	    net: phy: at803x: disable delay only for RGMII mode

Booting v5.1-rc1 with this commit reverted makes networking to work
fine again.
