This fixes bug AR-1904.
The original fix was only for current and not for edge kernel which caused
the patch being lost and made the problem reoccur.
.
According to the original PR#6117 the problem of 10mbps ethernot not working
has first been seen in the 5.15 armbian kernel caused by a rewrite of speed
setting for rk3308 in dwmc-rk.c that for unknown reasons completely omitted
the code needed to reprogram the MAC clock as appropriate for the selected
ethernet speed.
.
This patch corrects RK3308_GMAC_FLOW_CTRL and RK3308_GMAC_FLOW_CTRL_CLR to use
the correct bits for MAC onfiguration and restores the missing code needed for
setting the MAC clock required to match the selected ethernet speed.
