net: stmmac: Apply redundant write work around on 4.xx too
commit a3a57bf07de23fe1ff779e0fdf710aa581c3ff73 ("net: stmmac: work
around sporadic tx issue on link-up") worked around a problem with TX
sometimes not working after a link-up by avoiding a redundant write to
MAC_CTRL_REG (aka GMAC_CONFIG), since the IP appeared to have problems
with handling multiple writes to that register in some cases.
That commit however only added the work around to dwmac_lib.c (apart
from the common code in stmmac_main.c), but my systems with version
4.21a of the IP exhibit the same problem, so add the work around to
dwmac4_lib.c too.
Fixes: a3a57bf07de2 ("net: stmmac: work around sporadic tx issue on link-up")
