soc: zynqmp: increase SRAMP_PRIV MPU region size



openamp shared memory regions can be anywhere in DDR memory
withing 2G range. Current SRAM_PRIV region is 64M which
prevents access of shared memory (vrings) by RPU (cortex-r5)
if it is out of 64M range. This patch allows vrings to be in DDR within
2G address space.
