[PATCH -next] x86/apic: Reduce print level of CPU limit announcement

[Leon Romanovsky]

From: Leon Romanovsky <leonro@xxxxxxxxxxxx>

Kernel is booted with less possible CPUs (possible_cpus kernel boot
option) than available CPUs will have prints like this:

[    1.131039] APIC: NR_CPUS/possible_cpus limit of 8 reached. Processor 55/0x1f ignored.
[    1.132228] ACPI: Unable to map lapic to logical cpu number

Those warnings are printed for every not-enabled CPU and on the systems
with large number of such CPUs, we see a lot of those prints for default
print level.

Simple conversion of those prints to be in debug level removes them
while leaving the option to debug system.
