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.
