Subject: [PATCH v6 2/2] QE: remove PPCisms for QE

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@....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
