ARM ADIv5: CoreSight ROM decode part number and designer id

The existing arm_adi_v5.c code decodes CoreSight peripherals based
on the part number field.  However, these are specific to a
particular manufacturer (often ARM).  The same part number from
two different manufacturers (distinct designer ids) should not
decode as the same CoreSight peripheral.

The Analog Devices ADSP-SC58x and ADSP-BF70x have peripherals that
overlap with existing OpenOCD decoding.  The part number is the
same as existing OpenOCD decoding, but have a different JEP106 code.

Most, if not all, of the existing part number entries in
arm_adi_v5.c are probably specific to ARM. Change all entries
suspected to be designed by ARM to match only ARM's designer ID.

However, to preserve legacy behavior, existing non-ARM entries are
encoded with a wildcard so that they will behave in the same way as
the existing legacy code.  It is desirable, however, to start
encoding the data with designer codes to avoid such ambiguity.

Revising the code to check both the part number and designer id
seemed to a warrant a const array lookup table instead of a
multi-tiered switch statement.

Also try to sync part identification IDs with relevant ARM docs.
