pmap_mapdev: Consistently use vm_paddr_t for the first argument.

The devmap variants used vm_offset_t for some reason, and a few places
explicitly cast bus addresses to vm_offset_t. (Probably those casts
along with similar casts for vm_size_t should just be removed and
instead permit the compiler to DTRT.)

[ofw] fix errneous checks for OF_finddevice(9) return value

OF_finddevices returns ((phandle_t)-1) in case of failure. Some code
in existing drivers checked return value to be equal to 0 or
less/equal to 0 which is also wrong because phandle_t is unsigned
type. Most of these checks were for negative cases that were never
triggered so trhere was no impact on functionality.

sys/arm: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I

sys/arm: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Move arm's devmap to some generic place, so it can be used

Merge from head@274682

IFC @r271694

Sync to HEAD@r271160.

The ocotp driver provides access to registers containing chip configuration
data that is needed by other drivers, so make it an EARLY_DRIVER_MODULE()
that loads before just about anything else.

MFC @ r266724

An SVM update will follow this.

Merge head up to r262222 (last merge was incomplete).

Oops, remove some dregs of debugging.

Make it possible to access the ocotp registers before the ocotp device
is attached, by establishing a temporary mapping of the registers when
necessary. This is a temporary measure to keep progress

Make it possible to access the ocotp registers before the ocotp device
is attached, by establishing a temporary mapping of the registers when
necessary. This is a temporary measure to keep progress moving; in the
long run we need better control over the order in which devices attach
(better than "the order they appear in the fdt dts source").

Sweep up a couple crumbs left over from the imx6->fsl renaming.

It turns out Freescale cleverly made the ocotp device compatible across
several different families of SoCs, so move it to the freescale directory
and prefix everything with fsl rather than imx6.
