xilinx: kconfig: Change Kconfig dependencies for Xilinx drivers

Zynq/ZynqMP/Versal IPs should be possible to called also from Microblaze in
PL and vice versa. That's why change dependencies and do not limit enabling
just for some platforms.

This is follow up patch based on commit 664e16ce99a0 ("xilinx: kconfig:
