x86: Don't touch IA32_APIC_BASE MSR on Intel Quark

Intel Quark processor core provides an integrated Local APIC but
does not support the IA32_APIC_BASE MSR. As a result, the Local
APIC is always globally enabled and the Local APIC base address
is fixed at 0xfee00000. Attempting to access the IA32_APIC_BASE
MSR causes a general protection fault.
