[PATCH] x86/acrn: Remove redundant chars from ACRN signature

[Shuo Liu <shuo.a.liu@intel.com>]

hypervisor_cpuid_base() only handles 12 chars of the hypervisor
signature string but is provided with 14 chars.

Remove the redundancy. Additionally, replace the user space uint32_t
with preferred kernel type u32.
