bcm27xx: fix BCMGENET kernel config

Revert backported upstream commits 421f8663b3a7 and 8d820bc9d12b, which have
introduced a regression in BCMGENET kconfig that disabled the network driver
for the Raspberry Pi.

Fixes: 0c405bceba11 ("kernel: bump 5.15 to 5.15.85")
Fixes: e9008223268c ("kernel: bump 5.15 to 5.15.84")
