Simon Glass e3f8042575 ext4l: Add inode.c to build ...

Add inode.c to the Makefile with minimal changes:
- Replace Linux kernel includes with ext4_uboot.h
- Add cast in ext4_inode_peek_iversion() to fix const qualifier warning
- Add __maybe_unused to variables in ext4_print_free_blocks()

Update ext4_uboot.h with additional stubs needed by inode.c:
- address_space_operations: add migrate_folio, swap_activate members,
  fix write_begin/write_end/writepages signatures
- Add buffer_migrate_folio, buffer_migrate_folio_norefs, noop_dirty_folio

Add stub functions in stub.c for inode.c dependencies:
- Inline data: ext4_try_to_write_inline_data, ext4_generic_write_inline_data,
  ext4_write_inline_data_end
- xattr: ext4_xattr_delete_inode, ext4_xattr_inode_array_free
- JBD2: jbd2_inode_cache, jbd2_journal_try_to_free_buffers,
  jbd2_journal_init_jbd_inode

Also add required stub headers:
- linux/mpage.h - multi-page I/O stub
- linux/rmap.h - reverse mapping stub
- linux/atomic.h - atomic operations stub
