In order to be able to handle multiple devicetrees, do not assume
the tree to be unflattened is the barebox internal one. Instead,
just return a pointer to it and assign the barebox internal root_node
external to the unflatten function.

When the board is booted from NAND we have to setup the iomux to
make the SD card work. Unfortunately this still is not enough :(
The SD card still will only work when booting from it.

Support for ext filesystems has been introduced recently. We can now
boot directly from our rootfs, loading the kernel and device tree
images from /boot.

Since the only storage medium on the cfa-10036 is the MMC card, we need
to have a registered environment partition on it if we want to be able
to modify at runtime.

Refactor to remove duplicated code without changing functionality.
Put "then" on the same line of "if", because:
- is the most used style in barebox
- is like c code style
- is more compact
Reduce the number of lines from 50 to 40.
Tested on at91sam9260ek.

Using IS_ENABLED instead of #if/#ifdef the compiler can check
all the code.
Using IS_ENABLED for configuring smc->mode is an optimization,
reduce init.o text from 905 to 877.

Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.
This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

This is a rework of CLPS711X low level initialization code which includes:
- Prepare for changing CPU PLL multiplier from board lowlevel code.
- Decrease initial memory size to 8MB. It is minimal known size.
- Fix SDRAM initialization comment about size.
- Turn off all peripherals on startup.
- Skip PLL initialization if CPU is running from external 13 MHz clock.
- Use correct CPU speed for older CPUs without PLL.

On ArchosG9 the second stage low-level init was the fallback default.
Now that the low-level init is forcibly enabled it has to be skipped
when already executed from first stage.

if you use 1GiB of ram you can run the same barebox on Cortex-A15 or Cortex-A9
otherwise use vexpress_ca9_defconfig where the TEXT_BASE is at 0x63f00000
when we will add the relocation support this defconfig will be drop
