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

v7:
    - add single trailing underscore for internal variabled in macro.
      (suggested by Jan Beulich)
    - add parentheses for input parameters of marcro.
      (suggested by Jan Beulich)
    - adjust the postion of macro.
      (suggested by Jan Beulich)
v6:
    - move macro definition into the function and undefine it after use.
      (suggested by Roger Pau Monné)
    - do not bump sysctl version because it has been bumped for 4.10.
      (suggested by Roger Pau Monné)
v5:
    - remove domctl version number upgrade.
      (suggested by Jan Beulich)
    - restore 'XEN_SYSCTL_PSR_CAT_L3_CDP'.
      (suggested by Jan Beulich)
    - define a local macro to complete psr get value flow.
      (suggested by Roger Pau Monné)
    - remove 'Reviewed-by' and 'Acked-by'.
      (suggested by Wei Liu)
v4:
    - remove 'ALLOC_' from names.
      (suggested by Roger Pau Monné)
    - fix comments.
      (suggested by Roger Pau Monné)
v3:
    - remove 'op/OP' from names and modify some names from 'PSR_CAT' to
      'PSR_ALLOC'.
      (suggested by Roger Pau Monné)
v1:
    - add description about what to be changed in commit message.
      (suggested by Wei Liu)
    - bump sysctl/domctl version numbers.
