[media] coda: update CODA7541 to firmware 1.4.50
This patch splits the global workbuf into a global tempbuf and a per-context workbuf, adds the codec mode aux register, and restores the work buffer pointer on commands. With the new firmware, there is only a single set of read/write pointers which need to be restored between context switches. This allows more than four active contexts at the same time. All auxiliary buffers are now allocated through a helper function to avoid code duplication.
