x86/resctrl: Bring cbm_validate() into the resource structure
Bring all the functions that are different between the vendors into the
resource structure and initialize them dynamically. Add _intel suffix to
the Intel-specific functions.
cbm_validate() which does cache bitmask validation, differs between the
vendors as AMD allows non-contiguous masks. So, use separate functions
for Intel and AMD.
[ bp: Massage commit message and fixup rdt_resource members' vertical
alignment. ]
