locking/atomic: centralize generated headers
The generated atomic headers are only intended to be included directly by <linux/atomic.h>, but are spread across include/linux/ and include/asm-generic/, where people mnay be encouraged to include them. This patch centralizes them under include/linux/atomic/. Other than the header guards and hashes, there is no change to any of the generated headers as a result of this patch.
