Subject: [PATCH 1/2] x86/apic: Remove duplicate judgement of X86_64 in lapic_is_integrated()

The macro APIC_INTEGRATED(x) has already wrapped by CONFIG_X86_32. So
Invoke it directly.

But lapic_is_integrated() invokes APIC_INTEGRATED(x) with the duplicate
judgement of X86_64.

Remove the "#ifdef CONFIG_X86_64...". No functionality change.
