Subject: [PATCH v6 00/12] Enable jpeg enc & dec multi-hardwares for MT8196

This series have the follow changing:
Firstly fix some bugs, including resolution change handleing, stop
streaming sw flow, fix buffer layout and clock setting to support multi-hw
jpeg working and others.
Secondly add mt8196 jpegdec and jpegenc compatible to support MT8196
kernel driver.
Lastly, Add smmu setting to support smmu and iommu at the same time.

This series has been tested with MT8196 tast test.
Encoding and decoding worked for this chip.

Patches 1 fix jpeg hw count setting to support different chips.
Patches 2 fix jpeg buffer payload setting to handle buffer
size bug while resolution changed.
Patches 3 fix jpeg dst buffer layout.
Patches 4 fix multi-core stop streaming flow
Patches 5 fix multi-core clk suspend/resume setting
Patches 6 fix decoding buffer number setting timing issue
Patches 7 fix decoding resolution change operation
Patches 8 fix remove buffer operation
Patches 9-11 Adds jpeg encoder and decoder compatible.
Patches 12 add jpeg smmu sid setting.
