[ Upstream commit 42ef11b2bf ]

Correct supported speed modes as per the XGMAC databook.
Commit 9cb54af214 ("net: stmmac: Fix IP-cores specific
MAC capabilities") removes support for 10M, 100M and
1000HD. 1000HD is not supported by XGMAC IP, but it does
support 10M and 100M FD mode for XGMAC version >= 2_20,
and it also supports 10M and 100M HD mode if the HDSEL bit
is set in the MAC_HW_FEATURE0 reg. This commit enables support
for 10M and 100M speed modes for XGMAC IP based on XGMAC
version and MAC capabilities.
