Resolve warnings caused by incorrect kernel config settings (#3104)

* Remove all non-existing kernel config symbols

* Remove unapplied x86 Intel sound options

These are missing various subsystem dependencies and were never in fact
enabled, assuming they're rather exotic and removing them completely.

* Add missing dependencies, adjust tristate values, remove nonsense

* Use KERNEL_LZ4 only for non-aarch64

Since aarch64 doesn't use self-extracting kernel:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/[email protected]/

* Extract PCI options to device-support-pci fragment (renamed from device-support-pcie)

RPi 4+ should use this fragment too, since CM4 has PCIe support.

* Rename RPi's kernel-32b fragment to kernel-armv7
