soc/amd/common/block/pi/heapmanager.c: Simplify code

There are sections of code that are almost identical and they can be
converted to auxiliary procedures. For allocating heap, 3 sizes (the
buffer size of currently being examined node, the buffer size of the
current best fit node and the minimum size for a buffer that will need
to be split if selected as the best fit) are used often so they could
be stored in temporary variables. These 2 changes will make code shorter,
with less indentation problems and overall easier to read. The actual
logic of the code is not changed.
