cpu_v2_3: Generate parameters specifically for psu_microblaze

Browse source 
PMU Microblaze related parameters are generated into xparameters.h based on the IP parameters.
This tcl generates parameters with prefix XPAR_MICROBLAZE so that they can be used with generic microblaze bsp/drivers.
Clock frequency param is also generated based on C_FREQ param of psu_microblaze IP.
