clk: imx: scu: fix MXC_CLK_SCU module build break

This issue can be reproduced by having a kernel config with
CONFIG_IMX_MBOX=m and CONFIG_MXC_CLK_SCU=m. It's caused by the Makefile
wanting to build clk-scu.o and clk-imx8qxp.o as different targets but
that doesn't work (e.g. MXC_CLK_SCU = y while CLK_IMX8QXP = n)

"obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o clk-imx-lpcg-scu.o
clk-imx-scu-$(CONFIG_CLK_IMX8QXP) += clk-scu.o clk-imx8qxp.o"

Having MXC_CLK_SCU=y/m while CLK_IMX8QXP=n will cause a linker problem
like below:

LD [M] drivers/clk/imx/clk-imx-scu.o
arm-poky-linux-gnueabi-ld: no input files

Make MXC_CLK_SCU be un-selectable by users so it can only be selected by
the CLK_IMX8QXP option, ensuring the two symbols are built together.
Drop COMPILE_TEST too because this option isn't selectable anymore. We
can remove it from MXC_CLK_SCU because CLK_IMX8QXP selects MXC_CLK_SCU
which already has COMPILE_TEST.
