The s3c_gpio_cfgall_range() function is an internal interface of
the samsung gpio driver and should not be called directly by drivers,
so move the iis pin initialization into the boards.

Note that the s3c2412-i2s driver has no boards using it in
mainline linux, the driver gets selected for the jive machine
but is never instantiated.

Right, I've added an explanation in the changelog text now:

 The s3c_gpio_cfgall_range() function is an internal interface of the
 samsung gpio driver and should not be called directly by drivers, so
 move the iis pin initialization into the boards.

+This means the pin configuration is only run once at early boot, rather
+than each time the driver binds, but the effect should be the same.
