21f2375346 clk: zynqmp: Drop dependency on ARCH_ZYNQMP 
The clock driver depends on ZYNQMP_FIRMWARE which in turn depends on
ARCH_ZYNQMP. Simplify the Kconfig by dropping the redundant dependency
on ARCH_ZYNQMP as it'll be applied transitively via ZYNQMP_FIRMWARE.

c3ce6a4a81 clk: zynqmp: Enable the driver if ZYNQMP_FIRMWARE is selected 
When booting the kernel on zynqmp based platforms such as Ultra96v2,
peripheral drivers such as that for the sdcard depend on the presence
of clocks.

Enable the clock driver if it's dependencies are compiled to avoid
building an unbootable kernel.
