[PATCH] soc: fsl: cpm1: qmc: Fix dependency on fsl_soc.h

[Christophe Leroy]

QMC driver requires fsl_soc.h to use function get_immrbase().
This header is provided by powerpc architecture and the functions
it declares are defined only when FSL_SOC is selected.

Today the dependency is the following:

	depends on CPM1 || QUICC_ENGINE || \
		   (FSL_SOC && (CPM || QUICC_ENGINE) && COMPILE_TEST)

This dependency tentatively ensure that FSL_SOC is there when doing a
COMPILE_TEST.

CPM1 is only selected by PPC_8xx and cannot be selected manually.
CPM1 selects FSL_SOC

QUICC_ENGINE on the other hand can be selected by ARM or ARM64 which
doesn't select FSL_SOC. QUICC_ENGINE can also be selected with just
COMPILE_TEST.

It is therefore possible to end up with CPM_QMC selected
without FSL_SOC.

So fix it by making it depend on FSL_SOC at all time.

The rest of the above dependency is the same as the one for CPM_TSA on
which CPM_QMC also depends, so it can go away, leaving only a simple
dependency on FSL_SOC.
