[IA64] Provides right frequency ratio and base for VTi domain

This patch handles the pal_freq_ratio and pal_freq_base request breaked
to Xen by GFW for VTi domain.  and it fixed the wrong frequency ratio
and base  of VTi domian.  So,i with this patch, VTi domian can get the
right time ,itc,cpu frequency, freqency base and other kernel params rely
on right frequency_ratio.
