While seeking, the driver calls the flush command. Before the flush
command is sent to the VPU, the driver should handle the display buffer
flags and should get all decoded information from the VPU if the VCORE
is running.

Add support for runtime suspend/resume in the encoder and decoder. This is
achieved by saving the VPU state and powering it off while the VPU is idle.

The display frame region information received from the vpu also
contains the frame display index: info->index_frame_display.
This index, being a s32, can be negative when a skip option is passed.
In that case, its value is DECODED_IDX_FLAG_SKIP (-2).
When disp_idx == -2, the following exception occurs:

Add the vpuapi layer of the wave5 codec driver.
This layer is used to configure the hardware according
to the parameters.
