MFC 265852: Map device memory using PTE_DEVICE rather than PTE_NOCACHE.

MFC r257199, r257200, r257217:

Remove all #include <machine/pmap.h> from arm code. It's already
included by vm/pmap.h, which is a prerequisite for arm/machine/pmap.h
so there's no reason to ever include it directly.

Remove #include <machine/frame.h> from all the arm code that doesn't
really need it. That would be almost everywhere it was included. Add
it in a couple files that really do need it and were previously getting
it by accident via another header.

Remove the last dregs of trapframe_t. It turns out only arm was using
this type, so remove it to make arm code more consistant with other
platforms.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Convert Marvell ARM platforms to FDT convention.

The following systems are involved:

- DB-88F5182
- DB-88F5281
- DB-88F6281
- DB-78100
- SheevaPlug

This overhaul covers the following major changes:

- All integrated peripherals drivers for Marvell ARM SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

Eliminate platform_pmap_init() to simplify Marvell bootstrap code.

Move the memory layout definitions and logic from mvreg.h to mvwin.h
so that it isn't exposured unless needed. In particular this means
that it's easier to tune the memory layout based on board details.
While here, remove inclusion of <machine/intr.h> from mvreg.h. This
also contains exposure to SoC specifics in MI drivers, because NIRQ
depends on the SoC.

Improve Marvell SOCs PCI/PCIE driver.

- Provide dedicated rmans for MEM and IO resources.

- Convert PCI IRQ routing info into a table (from callback approach), provide
config data for alternative DB- boards.

- Fix a wrong boundary check error in pcib_mbus_init_bar()

Improve and extend Marvell SOCs platform code.

- Allow for setting per platform MPP/GPIO configuration in the kernel, so
that we can override all settings firmware might set.

- Set decode windows for the remaining on-chip peripherals: CESA, SATA and XOR.

- Improve handling of USB controllers so that all port are available on the
given SOC/platform (e.g. up to three on DB-78xxx), this includes rework of
USB decode windows set-up.

- Other minor fixes and cosmetics.

PCI/PCI-Express support for Marvell systems.

Obtained from: Marvell, Semihalf

Introduce basic support for Marvell families of system-on-chip ARM devices:

* Orion
- 88F5181
- 88F5182
- 88F5281

* Kirkwood
- 88F6281

* Discovery
- MV78100

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:

* GPIO
* Interrupt controller
* L1, L2 cache
* Timers, watchdog, RTC
* TWSI (I2C)
* UART

Other peripherals drivers will be introduced separately.
