brcm2708: remove useless patches
The first adds some stuff while the second one just reverts it. Remove both patches. This is done is a separate commit on purpose to make it clear. Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>

-Subject: [PATCH 748/806] net: bcmgenet: Workaround for Pi 4B network issue
-
-Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
-DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
-address.
-
-Forcing renegotiation has been found to be an effective workaround, so
-add an automatic renegotiation after the link comes up for the first
-time; enable it with genet.force_reneg=y - by default it is disabled.
-
-See: https://github.com/raspberrypi/linux/issues/3108
