stm32mp1: ram: fix address issue in 2 tests
If user choose to test memory size is 1GByte (0x40000000), memory address would overflow in test "Random" and test "FrequencySelectivePattern". Thus the system would hangs up when running DDR test. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Signed-off-by: Bossen WU <bossen.wu@st.com>
