soc: fsl: cpm1: qmc: Fix dependency on fsl_soc.h

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.

soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation

Add support for the QMC (QUICC Multichannel Controller) available in
some PowerQUICC SoC that uses a QUICC Engine (QE) block such as MPC8321.

This QE QMC is similar to the CPM QMC except that it uses UCCs (Unified
Communication Controllers) instead of SCCs (Serial Communication
Controllers). Also, compared against the CPM QMC, this QE QMC does not
use a fixed area for the UCC/SCC parameters area but it uses a dynamic
area allocated and provided to the hardware at runtime.

Add support for the time slot assigner (TSA) available in some
PowerQUICC SoC that uses a QUICC Engine (QE) block such as MPC8321.

The QE TSA is similar to the CPM1 TSA except that it uses UCCs (Unified
Communication Controllers) instead of SCCs (Serial Communication
Controllers).
Also, compared against the CPM1 TSA, this QE TSA can handle up to 4 TDMs
instead of 2 and allows to configure the logic level of sync signals.

At a lower level, compared against CPM TSA implementation, some
registers are slightly different even if same features are present.

soc/fsl/qe: fix usb.c build errors

Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
being set. When USB_FSL_QE is set, QE_USB deafults to y, which
causes build errors when QUICC_ENGINE is not set. Making
QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.

Fixes these build errors:

soc: fsl: qe: remove PPC32 dependency from CONFIG_QUICC_ENGINE

There are also PPC64, ARM and ARM64 based SOCs with a QUICC Engine,
and the core QE code as well as net/wan/fsl_ucc_hdlc and
tty/serial/ucc_uart has now been modified to not rely on ppcisms.

So extend the architectures that can select QUICC_ENGINE, and add the
rather modest requirements of OF && HAS_IOMEM.

The core code as well as the ucc_uart driver has been tested on an
LS1021A (arm), and it has also been tested that the QE code still
works on an mpc8309 (ppc). Qiang Zhao has tested that the QE-HDLC code
that gets enabled with this works on ARM64.
