Prashanth Kumar KR 4bf22afe53 amd-xgbe: fix MAC_AUTO_SW handling in CL37 AN 
MAC_AUTO_SW (VR_MII_DIG_CTRL1 bit 9) enables automatic XPCS speed
mode switching after CL37 auto-negotiation and is only meaningful in
SGMII MAC mode. The original code unconditionally set this bit on
every call to xgbe_an37_set(), including when called from
xgbe_an37_disable() with enable=false. This left MAC_AUTO_SW=1 after
AN was disabled, causing the XPCS to autonomously switch speed from
stale AN state during subsequent mode changes, breaking SGMII speed
negotiation on 1G copper SFP modules.

Patrick: This was breaking negotiation for all 1G SFP modules,
not just copper modules.

Fixes: 42fd432fe6 ("amd-xgbe: align CL37 AN sequence as per databook")
