hw/arm/realview.c: Fix memory leak in realview_init()
Variable 'ram_lo' is allocated unconditionally, but used only in some cases.
When it is unused pointer will be lost at function exit, resulting in a
memory leak. Allocate memory for 'ram_lo' only if it is needed.
Valgrind output:
==16879== 240 bytes in 1 blocks are definitely lost in loss record 6,033 of 7,018
==16879== at 0x4C2AB80: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
