It is nice to allow compile-testing the firmware drivers, but this fails when the dependency is a loadable module: aarch64-linux-ld: drivers/firmware/imx/scu-pd.o: in function `imx_sc_pd_power': scu-pd.c:(.text+0xd8): undefined reference to `imx_scu_call_rpc' aarch64-linux-ld: scu-pd.c:(.text+0x108): undefined reference to `imx_scu_call_rpc' aarch64-linux-ld: drivers/firmware/imx/scu-pd.o: in function `imx_sc_pd_probe': Change the dependencies to ensure that any driver we depend on is either reachable or we are compile-testing and it is disabled, effectively reverting most of the previous changes that turned out to be incorrect.

The System Controller Firmware (SCFW) is a low-level system function
|
|
which runs on a dedicated Cortex-M core to provide power, clock, and
|
|
resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
|

(QM, QP), and i.MX8QX (QXP, DX).

This driver manages the IPC interface between host CPU and the

SCU firmware running on M4.
