This reduces .bss size by 8 KiB, and should reduce overall memory usage
since most platforms will have significantly fewer than 512 entries in
this table. At the same time, it removes the fixed table size limit.
Since the table is only used within fdt_pmu.c, instead of updating the
extern declaration, make the table local to this file.

Distinguish between functions which modify the devicetree and those
which only extract information from it. Other than the iterators in
fdt_domain.c, this is a mechanical conversion.

To allow platform override pmu_init() filling the translation table
fdt_pmu_evt_select[] when PMU node doesn't provide such information,
we need to share the table and its entry counter with other .c file.
We also define the structures of PMU property in fdt_helper.h, so we
can initialize the mappings in arrays.

We update FDT support makefile to use kconfig for enabling/disabling.
To avoid compilation errors, we also enable FDT for each platform.

The PMU DT node bindings are defined in docs/pmu_support.md
Add few fdt helper functions to parse the DT node and update the
event-counter mapping tables.
