microblaze: Export xmb_manager functions

Browse Source 
[ Upstream commit badf752b5e4b17d281f93f409d4718388ff912e6 ]

When TMR_MANAGER is enabled as module there is a need to export functions
which are present in architecture code.

It has been found by running:
make W=1 C=1 allmodconfig
sed -i -e 's/WERROR=y/WERROR=n/g' .config
make C=1 W=1

which errors out like this:
ERROR: modpost: "xmb_manager_register" [drivers/misc/xilinx_tmr_manager.ko] undefined!
ERROR: modpost: "xmb_inject_err" [drivers/misc/xilinx_tmr_inject.ko] undefined!
