arm64: zynqmp: Add missing ZYNQMP_FIRMWARE dependencies

There are missing Kconfig dependencies in the code which is using
firmware interface.
The commit 71efd45a5fc7 ("arm64: zynqmp: Change firmware dependency")
add option to also disable ZYNQMP_FIRMWARE. But not all Kconfig
dependencies were properly described and also sdhci and gem drivers
didn't protect the code properly.
So, add the missing ZYNQMP_FIRMWARE dependencies.
