Add the KERNEL_BTRFS_FS config option so that targets can select
whether BTRFS support must be built-in.
Select this option (alongside KERNEL_BTRFS_FS_POSIX_ACL) from the
layerscape/armv8_64b subtarget instead of enabling it in
target/linux/layerscape/armv8_64b/config-* files.
Move disabling of CONFIG_BTRFS_FS_CHECK_INTEGRITY into generic configs.
This makes it possible for OpenWRT to be built with built-in BTRFS
support on specific boards, instead of whole targets.

Rename subtargets 32b/64b with armv8_32b/armv8_64b which are
more proper, and update makefile files. There also will be other
subtargets added in the future, like armv7.
