MIPS: bcm963xx: Move extended flash address to bcm_tag header file
The extended flash address needs to be subtracted from bcm_tag flash
image offsets. Move this value to the bcm_tag header file.
Renamed define name to consistently use bcm963xx for flash layout
which should be considered a property of the board and not the SoC
(i.e. bcm63xx could theoretically be used on a board without CFE
or any flash).
