			After making the brcmstb_gisb driver modular with707a4cdf86("bus: brcmstb_gisb: Allow building as module") Guenter reported that mips allmodconfig failed to link because board_be_handler was referenced. Thomas indicated that if we were to continue making the brcmstb_gisb driver modular for MIPS we would need to introduce a function that allows setting the board_be_handler and export that function towards modules. This is what is being done here: board_be_handler is made static and is now settable with a mips_set_be_handler() function which is exported.
