With this commit we can modify single values within an array of a dts
property.
This is useful if we have for example a pwm-backlight where we want to
modifiy the pwm frequency per u-boot script.
The pwm is described in dts like this:
backlight {
pwms = <0x0000002b 0x00000000 0x004c4b40>;
};
For changing the frequency, here the 3rd parameter, we simply type:
fdt set /backlight pwms <? ? 0x1E8480>;
For doing all this we:
- backup the property content into our 'SCRATCHPAD'
- only modify the array-cell if the new content doesn't start with '?'

The build output can still produce unicode encoded output. But in
the buildman's log and err files we only want plain ASCII characters.
To handle all situations with unicode and non-unicode output, encode
the stdout and stderr strings to UTF-8 and afterwards to ASCII with
replacing all special characters.

Build tools like Make, gcc or binutils support localized output
or unicode encoded output dependent on the default system locale.
This is not useful for buildman, where we want reproducible
warning or error messages or where the output of binutils is

Add remove() methods for EDP and VOP so that U-Boot can shut down the
video on exit. This avoids leaving DMA running while booting Linux which
can cause problems if Linux uses the frame buffer for something else.
It also makes it clear what is needed to shut down video.
While we are here, make rkvop_enable() static.

With xip booting configuration, we don't need to copy the next image
(U-Boot or linux xipimage) from flash to sdram area.
Flash memory organization is like this:
spl-U-Boot: u-boot-spl.bin : 0x0800_0000
U-Boot : u-boot-dtb.bin : 0x0800_8000
linux : xipImage : 0x0800_8000
It is also possible to have U-Boot binary & linux binaries configured at
different addresses of flash memory like U-Boot at 0x0800_8000 & linux
xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for
U-Boot as next binary with SPL_OS_BOOT option disabled.
By default, spl is configured to boot linux xipImage.
