[PATCH] interconnect: add license and exports to fix build errors

[Randy Dunlap <rdunlap@infradead.org>]

icc-clk.c should have a MODULE_LICENSE() and export its register and
unregister functions to prevent build errors, so add them.

ERROR: modpost: missing MODULE_LICENSE() in drivers/interconnect/icc-clk.o
ERROR: modpost: "icc_clk_unregister" [drivers/clk/qcom/clk-cbf-8996.ko] undefined!
ERROR: modpost: "icc_clk_register" [drivers/clk/qcom/clk-cbf-8996.ko] undefined!

Fixes: 0ac2a08f42ce ("interconnect: add clk-based icc provider support")
