x86/64/defconfig: Add CONFIG_IRQ_REMAP
x2apic is enabled in the defconfig, and interrupt remapping is an
architectural dependency of x2apic as per the Intel SDM:
Routing of device interrupts to local APIC units operating in x2APIC
mode requires use of the interrupt-remapping architecture specified in
the Intel® Virtualization Technology for Directed I/O (Revision 1.3
and/or later versions).
Enable CONFIG_IRQ_REMAP in defconfig so that a defconfig kernel on bare metal
actually uses x2apic.
