QE was supported on PowerPC, and dependent on PPC,
Now it is supported on other platforms. so remove PPCisms.
Signed-off-by: Zhao Qiang <qiang.zhao@nxp.com>
---
Changes for v2:
- na
Changes for v3:
- add NO_IRQ
Changes for v4:
- modify spin_event_timeout to opencoded timeout loop
- remove NO_IRQ
- modify virq_to_hw to opencoed code
Changes for v5:
- modify commit msg
- modify depends of QUICC_ENGINE
- add kerneldoc header for qe_issue_cmd
Changes for v6:
- add dependency on FSL_SOC and PPC32 for drivers
depending on QUICC_ENGING but not available on ARM
