[Buildroot] [PATCH] configs/qemu_riscv{32, 64}_virt_defconfig: Remove BR2_TARGET_GENERIC_GETTY_PORT

By doing this change, we need to check if -nographic is used to start qemu (so
the serial port is the default console) or if console=ttyS0 is used in the
kernel command line.

riscv32 and risc64 are both using -nographic to start Qemu.

Your use case is similar to the one from [1]
