Subject: [PATCH v6 2/4] mailbox: qcom-apcs-ipc: add IPQ8074 APSS clock controller support
Date:   Thu,  7 Jul 2022 19:37:31 +0200

IPQ8074 has the APSS clock controller utilizing the same register space as
the APCS, so provide access to the APSS utilizing a child device like
IPQ6018 does as well, but just by utilizing the IPQ8074 specific APSS
clock driver.

Changes in v6:
* Adjust max_register value using match data instead of globally

Changes in v5:
* Use lower case hex for max_register
* Update the APSS clock name to match the new one without commas
