The reset circuitry in the RK3399 only resets 'almost all logic' when
a software reset is performed. To make our software maintenance
easier in the future, we want to have the option (controlled by a DTS
property) to force all reset causes other than a power-on reset to
trigger a power-on reset via a GPIO trigger.
This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7)
board-support and the documentation for the new property
(sysreset-gpio) within the /config-node.

For some versions of the RK3399-Q7 (at least revisions v1.1 and v1.2
are affected), we need to turn on the power for the port connected to
the on-module USB hub only when the device is probed for the first
time to ensure that the hub does not enter a low-power mode (that
U-Boot's USB stack can't deal with).
Note that this is needed for U-Boot only, as Linux eventually manages
to attach the hub even when it has entered into its low-power state
(when the hub wakes up the next time) after a few seconds.

This commit updates the .its file for the RK3399-Q7 to use the new
features and demonstrates how to use those:
* it marks the ATF as the 'firmware'
* it tracks the OS-type for U-Boot and ATF
* it loads the PMU (M0) firmware to DRAM and records the location
to /fit-images (where our ATF reads it from)
With the handoff of the next-stage FDT to ATF in place, we can now use
this to pass information about the load addresses and names of each
loadables to ATF: now we can load the M0 firmware into DRAM and avoid
overwriting parts of the SPL stage. This is achieved by changing our
.its-file to use an available area of DRAM as the load-address.

The (Qseven) BIOS_DISABLE signal on the RK3399-Q7 (Puma) keeps the
eMMC and SPI in reset initially and we need to write a GPIO to turn
them on before continuing the boot-up.
This adds the DTS entries for the additional regulator and makes
pinctrl and gpio3 available during SPL. It also adds a hook to the
spl_board_init() to ensure that the regulator gets probed and enabled.

The original initialisation code for board_init() was largely lifted
from the code on the EVB. However, the RK3399-Q7 can do with a much
more concise init sequence.
This cleans up the board_init() by updating it to the essentials for
the RK3399-Q7 and getting rid of the accumulated cruft.

The later-stage spl_board_init (as opposed to board_init_f) should set
up board-specific details: these differ between the EVB-RK3399 and the
RK3399-Q7 (Puma).
This moves spl_board_init back into the individual boards and removes
the unneeded functionality from Puma.

The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3399.
It provides the following feature set:
* up to 4GB DDR3
* on-module SPI-NOR flash
* on-module eMMC (with 8-bit interace)
* SD card (on a baseboad) via edge connector
* Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY
* HDMI/eDP/MIPI displays
* 2x MIPI-CSI
* USB
- 1x USB 3.0 dual-role (direct connection)
- 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub)
* on-module STM32 Cortex-M0 companion controller, implementing:
- low-power RTC functionality (ISL1208 emulation)
- fan controller (AMC6821 emulation)
- USB<->CAN bridge controller
Note that we use a multi-payload FIT image for booting and have
Cortex-M0 payload in a separate subimage: we thus rely on the FIT
image loader to put it into the SRAM region that ATF expects it in.
