treewide: Remove OF_PRIOR_STAGE

Browse source 
The previous patches removed OF_PRIOR_STAGE from the last consumers of the
Kconfig option.  Cleanup any references to it in documentation,  code and
configuration options.

Using binman with OF_BOARD or OF_PRIOR_STAGE
Using binman with OF_BOARD
--------------------------------------------
Normally binman is used with a board configured with OF_SEPARATE or OF_EMBED.
This is a typical scenario where a device tree source that contains the binman
node is provided in the arch/<arch>/dts directory for a specific board.
However for a board configured with OF_BOARD or OF_PRIOR_STAGE, no device tree
blob is provided in the U-Boot build phase hence the binman node information
is not available. In order to support such use case, a new Kconfig option
BINMAN_STANDALONE_FDT is introduced, to tell the build system that a standalone
device tree blob containing binman node is explicitly required.

OF_PRIOR_STAGE to generate u-boot.itb image.
