[PATCH v4 1/3] media: iris: cache work mode after computing it in iris_set_stage

[Sachin Kumar Garg <sachin.garg@oss.qualcomm.com>]

iris_set_stage() computes work_mode and sends it to firmware but
never updates inst->fw_caps[STAGE].value, leaving the cached STAGE
value stale. iris_vpu_enc_bin_size() and
iris_vpu3x_vpu4x_calculate_frequency() read this cached value, so a
stale default causes them to miscalculate buffer size and clock
frequency for sessions actually running in a different stage than
the cached one.

Update inst->fw_caps[cap_id].value with the computed work_mode
before sending it to firmware, keeping the cache consistent with
what is actually configured.

Fixes: 3a19d7b9e08b ("media: iris: implement set properties to firmware during streamon")
