media: venus: pm_helpers: add fallback for the opp-table

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.
