[PATCH net] net: ti: icssg-prueth: Fix 10M Link issue on AM64x

[MD Danish Anwar]

Crash is seen on AM64x 10M link when connecting / disconnecting multiple
times.

The fix for this is to enable quirk_10m_link_issue for AM64x.

Fixes: b256e13378a9 ("net: ti: icssg-prueth: Add AM64x icssg support")

NOTE: If quirk_10m_link_issue is set, the ICSSG driver enables IEP1 which
fixes the 10M link issue.

As per Roger Quadros <rogerq at kernel.org> 's suggestion [1], posting this
as a separate patch.
