cmd: pxe: add support for FIT config selection
Add a way in configuration files (exlinux.conf for sysboot command)
to select a specific FIT configuration. The configuration is selected
with a string added after the FIT filename in the label "KERNEL" or
"LINUX", using the same format than bootm command:
KERNEL [Filename]#<conf>[#<extra-conf[#...]]
This configuration string, beginning by '#', is directly appended
to bootm argument 1 after <kernel_addr_r>.
bootm [<kernel_addr_r>]#<conf>[#<extra-conf[#...]]
see doc/uImage.FIT/command_syntax_extensions.txt for details
Example :
KERNEL /fit.itb#cfg1
KERNEL /fit.itb#cfg2
Configuration can be use also for overlay management :
KERNEL /fit.itb#cfg1#dtbo1#dtbo3
see doc/uImage.FIT/overlay-fdt-boot.txt for details
