boards: arm: mps2_an521: remove the arm,num-mpu-regions property

Browse source 
The SSE-200 implementation on AN521 only has 8 regions.
Although the AN521 FPGA image implements the documented value,
qemu-system-arm currently shows in MPU_TYPE the incorrect value of 16.

Removing the property definition allows the code to rely on the register
read value and work on both qemu-system-arm & the physical board.
