In particular, for a given platform (x86, AMD64...) its definition
depends for uniprocessor vs. multiprocessor NT kernel/HAL (controlled
by the CONFIG_SMP define).
Regarding the ASM-generated headers (from asm/ksx.template.h), since
they are generated once for a given platform, and since UP/MP NT builds
are generated at the same time, these headers need to contain both
SYNCH_LEVEL definitions controlled by CONFIG_SMP, instead of a fixed
value. Therefore we need to employ the geninc RAW(...) construct.
[NDK:X86] Add missing x86 CLOCK1_LEVEL and POWER_LEVEL definitions.
