By exporting a couple more variables the wks file for every rockchip device
can be built from one template instead of having separate wks files for each
board and platform.
The following BSP variables were checked before and after this change to make
sure they remained valid/sensible:
- WKS_FILE
- UBOOT_SUFFIX
- SPL_BINARY
- IMAGE_FSTYPES
Built-tested for every MACHINE in this BSP.
Run-tested on the following devices to ensure they continue to boot correctly
to a cmdline (core-image-base):
- tinker-board
- rock-pi-e
- rock-pi-4b
- rock64
- nanopi-m4-2gb

The --align argument isn't intended to make a partition exist at a fixed
location like the Rockchip boot ROM requires. Use the recently added
--offset argument which will fail to build the image if the partition
can't be placed at the correct location. Also used --fixed-size to make
sure that Wic isn't inserting hidden padding that changes things around.
Finally, the location of the rootfs isn't required to be at sector
262144 since u-boot and the kernel reads the partition table to find it
and actually hasn't been at this location anyway since Wic has been
padding the /boot partition, so remove it's alignment requirements.

wic modifies /etc/fstab on the root file system during image generation,
without the --ondisk parameter it assumes some default device name which
leads to an /etc/fstab file populated with /dev/sda entries.
This is not correct for the machines in the rockchip layer which use
mmcblkX.
This patch introduces an RK_BOOT_DEVICE option which is being set in the
machine configuratoin and which is being used in the wks files.
The variable expansion in the wks is handled by propagating the variable to
the wic environment.
This results in correct /etc/fstab entries and in a correct kernel
bootargs root= parameter.

Adds support for the rk3399 SoC. Notably:
*) Split out the default kernel config and image type from
rockchip-defaults.inc now that not all support chips are ARMv7
*) Apply a patch to Arm Trusted Firmware to fix a compile issue
*) Arm Trusted Firmware requires the arm-none-eabi-native compiler to
compile the M0 firmware.
*) Modify u-boot to pull in the ATF files when compiling
*) The rk3399 is support by the panfrost driver in mesa, so enable it
