[U-Boot] [PATCH] driver: net: fsl-mc: Fix DPC MAC address fixup

[Ioana Ciocoi Radulescu]

If node /board_info/ports does not exist in the DPC file,
function mc_fixup_dpc() will skip not only MAC address fixup,
but also the cache flush at the end. This may cause the other
fixup changes (e.g. ICID relatd ones) to be ignored by MC.

Fixes: 1161dbcc0a36 ("drivers: net: fsl-mc: Include MAC addr fixup to DPL")
