[PATCH] MIPS: lantiq: export clk_get_io() for lantiq_wdt.ko

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

The lantiq WDT driver uses clk_get_io(), which is not exported,
so export it to fix a build error:

ERROR: modpost: "clk_get_io" [drivers/watchdog/lantiq_wdt.ko] undefined!

Fixes: 287e3f3f4e68 ("MIPS: lantiq: implement support for clkdev api")
