spec/xilinx-zynqmp-rpu: Calculate correct RAM area

Browse Source 
There were some problems in the math calculating RAM length and NOCACHE
origin location. These have been resolved in this patch allowing RTEMS
RAM space to be relocated above 0xfe00000 to better accomodate other
elements in the system.
