Subject: [PATCH] Provides right frequency_ratio for VTi domain

Hi Dan,
        This patch handles the pal_freq_ratio request breaked to Xen by GFW for 
VTi domain. and it fixed the wrong frequency_ratio of VTi domian.So,with this 
patch, VTi domain can get the right time , itc, cpu frequency and other kernel 
params rely on right frequency_ratio. Please help to check in. thx.
