Integrate Capacity and Bandwidth Controller QoS Register Interface

[rpsene]

Capacity and Bandwidth Controller QoS Register Interface was ratified back in 2024, and its integration into the main document is pending, given it is a non-ISA specification. This issue aims to track its integration.

Capacity and Bandwidth Controller QoS Register Interface ratification package had three parts:

1. Ssqosid ISA extension
2. IOMMU extension for CBQRI
3. CBQRI non-ISA extension

#1 is integrated into the Priv. ISA manual via this PR: #1331
#2 is integrated into the IOMMU specification via this PR: riscv-non-isa/riscv-iommu@0076b5f

#3 is a non-ISA specifciation and does not integrated into the ISA manual.

Please let me know is anything else is pending integration.
