[PATCH v2] media: venus: pm_helpers: add fallback for the opp-table

[PATCH v2] media: venus: pm_helpers: add fallback for the opp-table

[Renjiang Han]

Since the device trees for both HFI_VERSION_1XX and HFI_VERSION_3XX
do not include an opp-table and have not configured opp-pmdomain, they
still need to use the frequencies defined in the driver's freq_tbl.

Both core_power_v1 and core_power_v4 functions require core_clks_enable
function during POWER_ON. Therefore, in the core_clks_enable function,
if calling dev_pm_opp_find_freq_ceil to obtain the frequency fails,
it needs to fall back to the freq_tbl to retrieve the frequency.

Validated this series on QCS615 and msm8916.

Changes in v2:
- 1. Update the returned error value as per the feedback.
- Link to v1: https://lore.kernel.org/r/20250723-fallback_of_opp_table-v1-1-20a6277fdded@quicinc.com
