ARM: zynq: Setup stack size via Kconfig

Browse Source 
Stack size has been introduced by commit a69814c815 ("arm64: zynqmp:
Set initrd_high to as high as possible") and commit 085201c246 ("arm64:
versal: Set initrd_high to as high as possible")
to support setting up initrd_high as high as possible.
The same change should happen for Zynq because the code is moved to xilinx
common location.
