Subject: [PATCH v6 8/9] soc: qcom: cpr3: Add IPQ9574 definitions
From: Praveenkumar I <quic_ipkumar@...cinc.com>
* Add thread, scaling factor, CPR descriptor defines to enable
CPR on IPQ9574.
* Skip 'acc' usage since IPQ9574 does not have acc

v6: Rebase on top of Konrad's v15
- https://lore.kernel.org/lkml/20240708-topic-cpr3h-v15-0-5bc8b8936489@linaro.org/T/
v5: Move the 'acc_desc' usage check to first patch
v4: s/silver//, s/cprh/cpr4/
Skip 'acc' related code as IPQ9574 does not have acc
v3: Fix patch author
Included below information in cover letter
v2: Fix Signed-off-by order
