[PATCH v2 2/2] x86/defconfig: Add CONFIG_IRQ_REMAP

[Shashank Balaji <shashank.mahadasyam@sony.com>]

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.
