With a config having PAGE_SIZE set to 256K, BTRFS build fails
with the following message

 include/linux/compiler_types.h:326:38: error: call to '__compiletime_assert_791' declared with attribute error: BUILD_BUG_ON failed: (BTRFS_MAX_COMPRESSED % PAGE_SIZE) != 0

BTRFS_MAX_COMPRESSED being 128K, BTRFS cannot support platforms with
256K pages at the time being.

There are two platforms that can select 256K pages:
 - hexagon
 - powerpc

Disable BTRFS when 256K page size is selected.
