Select CONFIG_SPL_STACK_R for sunxi boards, this gives us much more

Besides being a good change to have on itself, this also paves the
way for switching to using malloc_simple in the SPL which cuts of
close to 4KiB of the SPL size.

sunxi: add "fel" boot target

This patch makes use of the previous changes to add a new "fel" boot
target for sunxi boards.

When booting via FEL, it's often desirable to work around the absence
of other (usable) boot devices - or to be able to override them,
deviating from the standard boot sequence. To achieve this, the "fel"
boot target gets the highest priority, but won't actually do anything
unless certain criteria are met.

The "bootcmd_fel" implementation proposed here first tests if an actual
FEL boot takes place (using the "fel_booted" env var), and secondly
checks that "fel_scriptaddr" was set (originating from the 'loader',
i.e. the sunxi-tools fel utility). If both checks pass, then it will
try to execute the boot script (boot.scr) at the given address. In case
of an error (e.g. an invalid image), the source command might return
"false", causing "distro_bootcmd" to proceed with the next boot target.

sunxi: Tweak various memory addresses

For the upcoming nand support we need a bigger heap, esp. ubi[fs] uses
quite a bit of memory, increase the heap size to 64 MB.

Our video code returns unused reserved framebuffer memory to the kernel
before booting it. Drop the #ifdef-ery and simply always reserve 16 MB.

Adjust bootm_size for the above changes.

We eventually want to add full nand support, since it makes no sense

Renaming the Kconfig option now makes things easier when we add full

kconfig: add config option for shell prompt

Add option to set shell prompt string from menuconfig and migrate
boards globally.

The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
files. This results in a streamlined default value across platforms, and
includes the following files: spear-common, sunxi-common, mv-common,
ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
not updated in their respective defconfig files under the assumption that
since they did not explicitly define a value, they're fine with whatever
the default is.
- On the other hand, boards that relied on a value defined in some
<boards>_common.h file such as woodburn_common, rpi-common,
bur_am335x_common, ls2085a_common, siemens_am33x_common, and
omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
assigning a value for CONFIG_SYS_PROMPT.

sunxi: Do not add a stdout-path alias to dts on boards without a serial port

Do not add a bogus (pointing to a non existing serial port) stdout-path
alias to dts on boards without a serial port.

Note that we still define CONS_INDEX as this is used by the SPL where we do
not use DM_SERIAL and thus CONFIG_REQUIRE_SERIAL_CONSOLE is not honored.

We are getting away with this because the sun5i die actually has
an uart0, which in the A13 package is not routed to the outside,
so we are simply sending SPL bootup messages to the tx pin at the
edge of the die, and they go no further from there...

And sofar we only have one A13 board which does not have a serial
port, all others do have a serial port. This kinda makes sense since
the A13 is a much lower pincount package compared to all the other
sunxi SoCs.
