When CONFIG_OF_EARLY_FLATTREE is disabled, there is a compiler
warning,

drivers/of/fdt.c:129:19: warning: ‘of_fdt_match’ defined but not used [-Wunused-function]
 static int __init of_fdt_match(const void *blob, unsigned long node,

Since the only caller of of_fdt_match() is of_flat_dt_match(),
let's move the body of of_fdt_match() into of_flat_dt_match()
and eliminate of_fdt_match().

Meanwhile, move of_fdt_is_compatible() under CONFIG_OF_EARLY_FLATTREE,
as all callers are over there.

Make the naming of units consistent with common practices:
  - Do not capitalize the first character of units ("Celsius" is
    special, as it is not the unit name, but a reference to its
    proposer),
  - Do not use plural for units,
  - Do not abbreviate "ampere",
  - Concatenate prefixes and units (no spaces or hyphens),
  - Separate units by spaces not hyphens,
  - "milli" applies to "degree", not to "Celsius".

Validating the examples against the schema have a few errors:

arm,gic.example.dt.yaml: 'ranges' does not match any of the regexes: '^v2m@[0-9a-f]+$', 'pinctrl-[0-9]+'
arm,gic.example.dt.yaml: #address-cells:0:0: 2 is not one of [0, 1]
arm,gic.example.dt.yaml: #size-cells:0:0: 1 was expected

'ranges' is valid, but missing from the schema, so add it. The reg
addresses and sizes don't match the schema requirements and the example
template. We could just override the example template to use 64-bit
addresses, but there's not really any value showing that in the example.
