5b2a2d008f src/*: normalize Google copyright headers
As per internal discussion, there's no "ChromiumOS Authors" that's
meaningful outside the Chromium OS project, so change everything to the
contemporary "Google LLC."

While at it, also ensure consistency in the LLC variants (exactly one
trailing period).

"Google Inc" does not need to be touched, so leave them alone.

24ae85c3ff libpayload/x86/apic: Add an apic_delay method and calibrate the timer
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().

ac8ebd0e73 libpayload/arch/x86: Add support for initializing the APIC
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.
