Subject: [PATCH] sys-kernel/coreos-modules: disable arm64 board specific
 kconfig settings

Disable ARCH_QCOM, ARCH_ZYNQMP, ARCH_MEDIATEK which enable other options that
are only relevant on the respective boards, none of which are supported targets
for Flatcar. Since the arm64 kernel does not support compression, these
settings have a significant impact on kernel size. The boot partition size is
only 128MB and needs to fit 2 kernels, so we have set ourselves a target of
60MB per kernel. This commit brings down the arm64 kernel size by 3MB.

At the same time, enable the settings that are actually relevant: ARCH_BCM,
because that one is relevant for Raspberry Pi 4 that runs Linux.
