perf/x86/intel/uncore: Add CBB PMON support for Diamond Rapids
On DMR, PMON units inside the Core Building Block (CBB) are enumerated
separately from those in the Integrated Memory and I/O Hub (IMH).
A new per-CBB MSR (0x710) is introduced for discovery table enumeration.
For counter control registers, the tid_en bit (bit 16) exists on CBO,
SBO, and Santa, but it is not used by any events. Mark this bit as
reserved.
Similarly, disallow extended umask (bits 32–63) on Santa and sNCU.
Additionally, ignore broken SB2UCIE unit.
