soc: fsl: cpm1: qmc: Introduce qmc_init_resource() and its CPM1 version

[ Upstream commit 727b3ab4 ]

Current code handles the CPM1 version of QMC. Resources initialisations
(i.e. retrieving base addresses and offsets of different parts) will
be slightly different in the QUICC Engine (QE) version. Indeed, in QE
version, some resources need to be allocated and are no more "staticaly"
defined.

In order to prepare the support for QE version, introduce
qmc_init_resource() to initialize those resources and isolate the CPM1
specific operations in a specific function.
