Making vmx_init a late initcall improves QEMU kernel boot times to
get to the init process. Average of 100 boots, QEMU boot average
reduced from 0.776 seconds to 0.622 seconds (~19.8% faster) on
Alder Lake i9-12900 and ~0.5% faster for non-QEMU UEFI boots.

[Take patch
and fix spelling of Alder Lake.]
