This patch renames PSR sysctl/domctl interfaces and related xsm policy to make them be general for all resource allocation features but not only for CAT. Then, we can resuse the interfaces for all allocation features. Basically, it changes 'psr_cat_op' to 'psr_alloc', and remove 'CAT_' from some macros. E.g.: 1. psr_cat_op -> psr_alloc 2. XEN_DOMCTL_psr_cat_op -> XEN_DOMCTL_psr_alloc 3. XEN_SYSCTL_psr_cat_op -> XEN_SYSCTL_psr_alloc 4. XEN_DOMCTL_PSR_CAT_SET_L3_CBM -> XEN_DOMCTL_PSR_SET_L3_CBM 5. XEN_SYSCTL_PSR_CAT_get_l3_info -> XEN_SYSCTL_PSR_get_l3_info The sysctl version number is bumped.
