fdt_init_reserved_mem() and fdt_reserved_mem_save_node() are private to
the DT code, so move there declarations to of_private.h. There's no need
for the dummy functions as CONFIG_OF_RESERVED_MEM is always enabled for
CONFIG_OF_EARLY_FLATTREE.

Reserved memory regions can be used for more than just DMA regions, so
only enabling on DMA_DECLARE_COHERENT (via HAS_DMA) or DMA_CMA is wrong.
This effectively doesn't matter except for the few cases arches select
NO_DMA.

At least, these users of RESERVEDMEM_OF_DECLARE depend on reserved memory
support:

arch/riscv/mm/init.c:RESERVEDMEM_OF_DECLARE(elfcorehdr, "linux,elfcorehdr", elfcore_hdr_setup);
drivers/memory/tegra/tegra210-emc-table.c:RESERVEDMEM_OF_DECLARE(tegra210_emc_table, "nvidia,tegra210-emc-table",
drivers/soc/fsl/qbman/bman_ccsr.c:RESERVEDMEM_OF_DECLARE(bman_fbpr, "fsl,bman-fbpr", bman_fbpr);
drivers/soc/fsl/qbman/qman_ccsr.c:RESERVEDMEM_OF_DECLARE(qman_fqd, "fsl,qman-fqd", qman_fqd);
drivers/soc/fsl/qbman/qman_ccsr.c:RESERVEDMEM_OF_DECLARE(qman_pfdr, "fsl,qman-pfdr", qman_pfdr);

Let's simplify things and enable OF_RESERVED_MEM when OF_EARLY_FLATTREE is
enabled.

Convert the current OMAP Mailbox binding from text format to YAML
format/DT schema, and delete the legacy text binding file.

The new YAML binding conversion is an updated version compared to
the original. The descriptions for certain properties have been
improved to provide more clarity. Constraints are added to the
properties 'ti,mbox-num-users', 'ti,mbox-num-fifos' and 'interrupts'.
The 'ti,hwmods' is a legacy property and is retained only to reflect
the existing usage on some older OMAP2 and OMAP3 platforms.

All the existing examples have also been updated to reflect the
latest dts nodes (ti,hwmods removed from OMAP4 and AM33xx examples,
and interrupts value updated for AM65x SoCs).
