Details:
Build kernel with default options, in which Power Management is enabled and cause Wakeup Event by SIC_IWR value.

Below is the log:

For BF533-EZKIT/BF533-STAMP, the same problem happens.
For BF561-EZKIT, Power Management is not supported and kernel building fails with Power Management enabled.

Fixed.
Only RTC interrupt can wake up deeper sleep core.

For BF533-EZKIT and BF533-STAMP, set SIC_IWR to 0x80, tests pass.
For BF537-EZKIT, set SIC_IWR to 0x8, tests pass.
So close this bug.
