Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_T

These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.
