Add stub headers to support ext4l filesystem compilation: New headers: - bit_spinlock.h: bit-based spinlock stubs - blkdev.h: block device structures and operations - buffer_head.h: buffer head management with state functions - crc32c.h: CRC32C checksum stub - fs.h: filesystem structures (super_block, inode operations) - journal-head.h: journal buffer head structure - mutex.h: mutex stubs Updates to existing headers: - compat.h: add rcu_head callback structure - jbd2.h: add wait.h and init.h includes for types - sched.h: add current task stub - workqueue.h: fix flush_work macro warning These provide the minimal Linux kernel interfaces needed for ext4 code to compile in U-Boot's single-threaded environment.
