This series adds support for multi hardware jpeg encoding, by first
adding use of_platform_populate to manage each hardware information:
interrupt, clock, register bases and power. Secondly add encoding
work queue to deal with the encoding requestsof multi-hardware
at the same time. Lastly, add output picture reorder function
interface to eliminate the out of order images.

This series has been tested with MT8195 Gstreamer.
Encoding worked for this chip.

Patches 1 Adds jpeg encoder dt-bindings for mt8195

Patches 2 jpeg encoder builds two module for using Multi-HW,
export some functions to make them visible by other modules.

Patches 3 use devm_of_platform_populate to manage multi-hardware.

Patch 4 add jpeg encoding timeout function to judge hardware timeout.

Patch 5 add encoding work queue to deal with multi-hardware encoding
at the same time.

Patch 6 add output picture reorder function to order images.

Patch 7 add stop cmd function to deal with EOS operation.
