In only RCA binary loading case, only default dsp program will be work
inside the chip.

v1:
- Split out the different logical changes into different patches.
- rename tasdevice_dsp_fw_state -> tasdevice_fw_state, the fw are not
only dsp fw, but also RCA(Reconfigurable data, such as acoustic data
and register setting, etc).
- Add TASDEVICE_RCA_FW_OK in tasdevice_fw_state to identify the state
that only RCA binary file has been download successfully, but dsp fw
is not loaded or loading failure.
- Add the this strategy into tasdevice_tuning_switch.
- If one side of the if/else has a braces both should in
tasdevice_tuning_switch.
- Identify whehter both RCA and DSP have been loaded or only RCA has
been loaded in tasdevice_fw_ready.
- Add check fw load status in tasdevice_startup.
- remove ret in tasdevice_startup to make th code neater.
