ARM: 6144/1: TCM memory bug freeing bug

Browse source 
This fixes a bug in mm/init.c when freeing the TCM compile memory,
this was being referred to as a char * which is incorrect: this
will dereference the pointer and feed in the value at the location
instead of the address to it. Change it to a plain char and use
&(char) to reference it.
