arch/x86/include/arch: fix assembly clobber for 64bit
the "x86 PIC code ebx" workaround done previously
by commit 689e31d18b0f ("Make cpuid functions usable
when compiled with PIC") does not work for x86_64
(the upper dword of rbx is set to 0)
the GCC bug that needed the workaround was fixed
in version 5 (see GCC bug 54232)
