Junichi Uekawa 8764deb8dd crosvm: Minimal change for manatee memory mapping. 
Do not map RAM to where the coreboot regions are.

Shift boot time GDT and IDT a bit to make way for coreboot region at
0..fff.

BUG=b:188011323
TEST=boot volteer-manatee
TEST=tast run rammus-arc-r arc.Boot.vm  # ARCVM still boots.
TEST=tast run rammus-arc-r crostini.Basic.bullseye_stable

volteer-manatee memory map:

after:

localhost ~ # dmesg | grep e820
[    0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable
