[PATCH net] net: phy: broadcom: Fix RGMII delays for BCM50160 and BCM50610M

[Florian Fainelli]

The PHY driver entry for BCM50160 and BCM50610M calls
bcm54xx_config_init() but does not call bcm54xx_config_clock_delay() in
order to configuration appropriate clock delays on the PHY, fix that.

Fixes: 733336262b28 ("net: phy: Allow BCM5481x PHYs to setup internal TX/RX clock delay")

Hi,

More (all) PHY entries that support RGMII should arguably do the same
thing here but given that we had a bad history of seeing broken
DTS/DTBs, I prefer to take a conservative approach here and submit a
localized fix to the hardware I just had to test this on.

While this dates back to before the commit in Fixes tag, that commit
introduces the bcm54xx_config_clock_delay() function and would make it
go far enough for stable back ports.
