[PATCH v4 4/5] x86/apic: Rename variable/function related to x86_io_apic_ops

The names of x86_io_apic_ops and its two member variables, are misleading. The .read member is to read IO_APIC reg, while .disable which hook native_disable_io_apic/irq_remapping_disable_io_apic is actually used to restore boot irq mode, not disable IO_APIC. So rename x86_io_apic_ops to x86_apic_o
