The firmware driver is optional, but the power driver depends on it,
which needs to be reflected in Kconfig to avoid link errors:
aarch64-linux-ld: drivers/soc/xilinx/zynqmp_power.o: in function `zynqmp_pm_isr':
zynqmp_power.c:(.text+0x284): undefined reference to `zynqmp_pm_invoke_fn'
The firmware driver can probably be allowed for compile-testing as
well, so it's best to drop the dependency on the ZYNQ platform
here and allow building as long as the firmware code is built-in.

Provides the driver to enable and disable the isolation between the

processing system and programmable logic part by using the logicoreIP
|

register set. This driver also configures the frequency based on the

clock information from the logicoreIP register set.

If you say yes here you get support for the logicoreIP.

If unsure, say N.
