	The apic_delay method will halt the CPU and wait for a timer interrupt to fire. I went with usec because nsec is too granular to guarantee. This method will be called from an arch_ndelay() method when the delay is large enough to justify a sleep. BUG=b:109749762 TEST=Tested it on grunt by changing the _delay method to call apic_delay().

2018-09-12	libpayload/arch/x86: Add support for initializing the APIC	Raul E Rangel
	This is just the bare minimum required to initialize the APIC. I only support xAPIC and chose not to support x2APIC. We can add that functionality later when it's required. I also made the exception dispatcher call apic_eoi so that the callbacks won't forget to call it. BUG=b:109749762 TEST=Booted grunt and verified that depthcharge continued to function and that linux booted correctly. Also verified GDB still works.
