platform: mtk: fix memory allocation problem

Because the size of struct comp_buffer has increased, the current heap
layout for the basic use case is not enough.

Some use cases are experiencing out of memory issues,
c0 memory  src/lib/alloc.c:765  ERROR failed to alloc 0x180 bytes zone
0x4 caps 0x1 flags 0x0

To fix this issue, we increase the number of 512-byte heap blocks to 32.
