nshlib: Add boot command

Browse Source 
boot [<image path> [<header size>]]

Boot a new firmware image. This command depends on hardware support
CONFIG_BOARDCTL_BOOT_IMAGE. <image path> may point to a partion or file
which contain the firmware to boot. The optional, numeric argument
<header size> may be useful for skipping metadata information preprended
to the firmware image.
