[WIP,RFC] Clean up spinlocks

This reverts commit 037ee4b5562099771795d52cf7149ddff8dd3595.

TBD: Breaks romstage co-operative threading, since those
need implementation of spin_lock() that is not a spinlock.

IMO commit a98d302fe9 x86/smp/spinlock: Disable thread coop when taking spinlock
is wrong and should be reverted too.
