[V2,0/7] Fixes jpeg crash issue in cuj test

[Irui Wang]

From: kyrie wu <kyrie.wu at mediatek.com>

This series is used to fix jpeg dec & enc crash in cuj test.
The problem was found frequently that executing CUJ
ui.EverydayMultiTaskingCUJ.*_ytmusic test cases on Tomato/Dojo
devices with the HW jpeg decoder enabled. Firstly the single core
and multi-core judgment methods were modified to make the driver
compatible with both cases. Secondly, the jpeg dec & enc worker
initialization method and the timing issue of remove buffer
were corrected, eliminating crash problems. Finally, some variables
and hw dev initialization methods are refactored to reduce code
redundancy and improve program robustness. 

This series has been tested with MT8195 & MT8188.
Jpeg encoding and decoding worked for these devices.

Patch 1 fixes single core and multi-core judgment methods.

Patch 2 optimized jpeg single core initial methods.

Patch 3 optimized sw flow of jpeg enc&dec worker to remove buffer.

Patch 4 reconstructs the initialization mode of worker.

Patch 5 Remove some unnecessary variables.

Patch 6 refactor some variables.

Patch 7 refactor hw dev initializaiton sw flow.
