[PATCH] x86: apic.c: xapic_icr_read and x2apic_icr_read should be static

[Jaswinder Singh Rajput <jaswinder@infradead.org>]

Impact: cleanup, reduce kernel size a bit, avoid sparse warning

Fixes sparse warning:
arch/x86/kernel/apic.c:270:5: warning: symbol 'x2apic_icr_read' was not declared. Should it be static?
