Support loading remoteproc firmware on IPQ9574 with the qcom_q6v5_wcss
driver. This firmware is usually used to run ath11k firmware and enable
wifi with chips such as QCN5024.
When submitting v1, I learned that the firmware can also be loaded by
the trustzone firmware. Since TZ is not shipped with the kernel, it
makes sense to have the option of a native init sequence, as not all
devices come with the latest TZ firmware.
Qualcomm tries to assure us that the TZ firmware will always do the
right thing (TM), but I am not fully convinced, and believe there is
justification for a native remoteproc loader. Besides, this series
has improvements to the existing code.
Changes since v1:
- Improve bindings following review feedback
- disable clocks on init failures in q6v7_wcss_reset()
- review-suggetsed readability improvements of qcom_q6v5_wcss
