[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.

Log:
[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.
