sm8250-common: Don't call configureRpcThreadpool for camera postproc impl

Browse source 
* In Android 12, no longer allowed to shrink the process pool after a
   larger process pool is started, we should patch camera postproc impl
   to nuke it from shrinking process pool and prevent triggering a fatal
   to cause the camera to crash.
   Ref: https://android.googlesource.com/platform/system/libhwbinder/+/8e047f7a626c782a02dc9e67dee2dbae35bc6956.

 * The following are the difference between before and after the
   patch.
   Before:
   MOV    W1, #1
   BL     ._ZN7android8hardware22configureRpcThreadpoolEmb
   Now:
   MOV    W1, #1
   NOP

 * Obtained by comparing the camera postproc impl modified by
   GitHub@erfanoabdi.

 * A tutorial on use hexdump, sed and xxd to patch hex in
   binary file: https://everydaywithlinux.blogspot.com/2012/11/patch-strings-in-binary-files-with-sed.html.
