Impact: cleanup
init_one_irq_desc() does not initialize the desc->lock properly -
you cannot init a lock by memcpying some other lock on it.
This happens to work right now (because irq_desc_init is never in use),
but it's a dangerous construct nevertheless, so fix it.

Impact: reduce printk noise
There were a couple of leftover KERN_DEBUG debugging printks, remove
them. Also clarify an error message.

Impact: reduce kconfig variable scope and clean up
Bartlomiej pointed out that the config dependencies and comments are not right.
update it depend to NUMA, and fix some comments

Impact: improve NUMA handling by migrating irq_desc on smp_affinity changes
if CONFIG_NUMA_MIGRATE_IRQ_DESC is set:
- make irq_desc to go with affinity aka irq_desc moving etc
- call move_irq_desc in irq_complete_move()
- legacy irq_desc is not moved, because they are allocated via static array
for logical apic mode, need to add move_desc_in_progress_in_same_domain,
otherwise it will not be moved ==> also could need two phases to get
irq_desc moved.
