[tkreuzer] 44894: [HAL] - Use spinlock.h from ntoskrnl, instead of duplicating the definitions - Use one spinlock.c, but compiled for 2 static libs (hal_generic_up and hal_generic_mp) - Move HalpAcquireSystemHardwareSpinLock and HalpReleaseCmosSpinLock to spinlock.c and use the inline functions for the kernel to make Arch happy.
