Currently Kconfig dependencies are used to allow non-interactive builds.
This leads to problems in Kconfig getting the dependencies right.
This patch adds a barebox_main function pointer which is called at the
end of the startup process. This defaults to run_shell when a shell is
enabled.
With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive
builds can now be enabled for every board allowing to compile a binary
without further Kconfig dependencies. This also allows for more flexibility,
for example boards may decide to try non-interactive startup first and
call run_shell if that fails.

We now have gpio_request. When we call gpio_direction_output before
registering a led_gpio the gpio will be implicitely requested by the
gpio core. gpio_request in the led core will then fail resulting in
an unregistered LED.
Fix this by removing the call to gpio_direction_output. The LED core
will do this anyway.

Fix size address calculation.
Global variables from <asm/sections.h> which are defined
in linker script *.lds files for end addresses has already
a +1 calculation.
For example:
stext = 0x100 with a size about 0x50 will result a etext = 0x150.
In this case a correct size calculation is (etext - stext) = 0x50.
In function 'request_sdram_region' the end address will be
calculated with (start + size - 1) which result a correct
end address of 0x149 in this example.
