When TSA is compiled as module the following error is reported:
"ucc_mux_set_grant_tsa_bkpt" [drivers/soc/fsl/qe/tsa.ko] undefined!
Indeed, the ucc_mux_set_grant_tsa_bkpt symbol is not exported.
Simply export ucc_mux_set_grant_tsa_bkpt.

When allowing this driver to be built for ARM, the build fails (for
CONFIG_SMP=y) since ARM's asm/irq.h header is not self-contained:
In file included from drivers/soc/fsl/qe/ucc.c:18:0:
>> arch/arm/include/asm/irq.h:34:50: error: unknown type name 'cpumask_t'
extern void arch_trigger_cpumask_backtrace(const cpumask_t *mask,
But nothing in this file actually uses anything from asm/irq.h -
removing this #include generates identical object code, both on PPC32
and on ARM (the latter with a patch added to asm/irq.h to make the
build work in the first place).

In preparation for allowing to build QE support for architectures
other than PPC, replace the ppc-specific io accessors by the qe_io*
macros. Done via

Make it clear that these operate on big-endian registers (i.e. use the
iowrite*be primitives) before we introduce more uses of them and allow
the QE drivers to be built for platforms other than ppc32.
