a2c75e964e media: chips-media: wave5: Fix a hang after seeking 
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.

2092b38334 media: chips-media: wave5: Support runtime suspend/resume 
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.

4e4103d6f3 media: chips-media: wave5: Fix panic on decoding DECODED_IDX_FLAG_SKIP 
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:

Move the disp_info assignment after testing that the index is positive
to avoid the exception.
