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. ]
