Some kconfig changes to reduce kernel size to avoid conflict of 0x8000 (kernel load address) + uncompressed kernel size (arch/arm/boot/Image) + compressed kernel size (arch/arm/boot/zImage) being bigger than 0x1e00000 (tags address). This causes mostly silent boot failures, with CONFIG_DEBUG_LL messages such as "no ATAGS support: can't continue" or "Error: invalid dtb and unrecognized/unsupported machine ID" can be seen on UART, though they're not very clear that the kernel image is essentially too big for what lk is setting up. Manual kconfig changes: * Convert some =y to =m to reduce kernel size, mostly NFS_FS and CIFS since those are quite big and there's no point in having them built-in. * Disable EXT2_FS & EXT3_FS - handled by EXT4 driver * Disable PCI - unused [ci:skip-build]: already built successfully in CI
