[PATCH] test/py: memtest: Fix test for non-trivial parameters

[Andrew Goodbody]

When using non-trivial values for parameters for this test it
will cause a spurious failure as the test passes a decimal value
to the mtest command which will interpret it as hexadecimal and
result in failure as below.

test/py/tests/test_memtest.py:66: in test_memtest_ddr
    assert expected_response in response
E   AssertionError: assert 'Tested 16 iteration(s) with 0 errors.' in 'Refusing to do empty test\r\nmtest - simple RAM read/write test\r\n\r\nUsage:\r\nmtest [start [end [pattern [iterations]]]]'
----------------------------- Captured stdout call -----------------------------
U-Boot> mtest 134217728 0x8001000 90 0x10
Refusing to do empty test
mtest - simple RAM read/write test
Usage:
mtest [start [end [pattern [iterations]]]]

The fix is to ensure that all the parameters to the mtest command are
passed as hexadecimal values.
