RVB23S64 Profile has extension name called "NEED_AN_EXTENSION_NAME_HERE"

[james-ball-qualcomm]

Looks like we need to capture this restriction in the RVB23S64 profile spec:

• If the hypervisor extension is implemented and pointer masking
  (Ssnpm) is supported then henvcfg.PMM must support at minimum,
  settings PMLEN=0 and PMLEN=7.

What's currently in the YAML:

NEED_AN_EXTENSION_NAME_HERE:
presence:
optional: expansion
version: "~>1.0"
when:
allOf:
- implemented: H
- implemented: Ssnpm
note: |
If the hypervisor extension is implemented
and pointer masking (Ssnpm) is supported
then henvcfg.PME must support at minimum, settings PMLEN=0 and PMLEN=7
