This series continues the work to reduce fs/ext4l/ext4_uboot.h by
moving definitions to their proper locations in include/linux/

The ext4l compatibility header started at 2584 lines. Previous work
reduced it to 1816 lines. This series further reduces it to 1677
lines by moving various definitions to appropriate headers:

- Block I/O flags (REQ_OP_*, REQ_SYNC, etc.) to linux/blk_types.h
- Block device flags (BLK_OPEN_*) to linux/blkdev.h
- Memory allocation flags (__GFP_*, SLAB_*) to linux/slab.h
- Scheduler stubs to linux/sched.h
- Process flags (PF_MEMALLOC*) to linux/sched.h
- System state definitions to linux/kernel.h
- Quota format constants to linux/quotaops.h
- STATX flags and struct kstat to linux/stat.h
- Timer definitions to new linux/hrtimer.h
- Inode mutex classes to linux/fs.h
- Various other small moves

This improves code organisation by placing definitions in headers
matching Linux kernel structure, making the codebase easier to
maintain and understand.
