not affected by CPU reset, so we need call shutdown_barebox()

When during tftp receive operation a ACK packet can't successfully be sent
the timer was resetted directly after send resulting in a deadlock.
This patch changes the timer reset operation in a way that it is only resetted
when the actually is progress, namely in the TFTP_ACK/TFTP_DATA pathes in the
tftp handler.

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.
