Currently the LVDS backlight does not work in U-Boot after a “reboot” comand
in the kernel.
This problem occurs because the kernel uses this pin in PWM mode and U-Boot
does not configure the backlight pin as GPIO functionality.
So fix the problem by explicitly configuring the backlight pin as GPIO in
U-Boot.

I noticed secondary CPUs sometimes fail to wake up, and the root
cause is that the sev instruction wakes up slave CPUs before the
preceding the register write is observed by them.
The read-back of the accessed register does not guarantee the order.
In order to ensure the order between the register write and the sev
instruction, a dsb instruction should be executed prior to the sev.

Some SPL loaders (like Allwinner's boot0, and Broadcom's boot0)
require a header before the actual U-Boot binary to both check its
validity and to find other data to load. Sometimes this header may
only be a few bytes of information, and sometimes this might simply
be space that needs to be reserved for a post-processing tool.
Introduce a config option to allow assembler preprocessor commands
to be inserted into the code at the appropriate location; typical
assembler preprocessor commands might be:
.space 1000
.word 0x12345678

Commit Notes:
Please note that the current code:
start.S (arm64) and
vectors.S (arm)
already jumps over some portion of data already, so this option basically
just increases the size of this region (and the resulting binary).
For use with Allwinner's boot0 blob there is a tool called boot0img[1],
which fills the header to allow booting A64 based boards.
For the Pine64 we need a 1536 byte header (including the branch
instruction) at the moment, so we add this to the defconfig.
