This patch series adds the listed features that have been missing
in upstream fastRPC driver.

- Add changes to support new enhanced invocation ioctl request.
- Add support for CRC check.
- Add polling mode support.

Userspace change: https://github.com/quic/fastrpc/pull/134
Patch [v1]: https://lore.kernel.org/all/20241007084518.3649876-1-quic_ekangupt@quicinc.com/

Changes in v2:
  - Moved context specific pointers under invoke_ctx structure to avoid
    code duplicacy.
  - Separated userspace and kernel data structures.
  - Changed design to address existing problems.
  - Added checks for reserved bits.
  - Dropped performance counter changes for now. I will rework and
    rework and submit it separately.
