[OpenPulse] PyDataMem_NEW_ZEROED is not declared

[doichanj]

Informations

• Qiskit Aer version: 0.4
• Python version: 3.7
• Operating system: Red Hat Enterprise Linux Server release 7.6 (ppc64)

What is the current behavior?

Compilation failure occurs on (only?) Power + RedHat environment because of Numpy's function "PyDataMem_NEW_ZEROED", maybe it is not implemented on this environment.
The error message is as follow (same 7 errors occur while compiling OpenPulse)

Steps to reproduce the problem

What is the expected behavior?

Suggested solutions

Could you please replace PyDataMem_NEW_ZEROED to PyDataMem_NEW that maybe supported on the Power + RedHat environment.
I googled PyDataMem_NEW_ZEROED, but it seems very few people uses this function, so I think using PyDataMem_NEW is a common way.

One has to be a bit careful as some routines might be expecting a zeroed memory.
