platform: imx: Increase system runtime heap size 

The introduction of the DMA multi channel domain made it so the cascaded
interrupt handling fails to allocate memory from this heap. Increasing
the size of the system runtime heap will allow the registering of
cascaded interrupts (and in particular the EDMA interrupt within the DMA
scheduling domain) to continue.

On this platform we have 8MB of total memory. Allocating 24kB instead of
12kB for the system runtime heap does not cause any noticeable change
besides removing the memory allocation failures.
