Subject: [PATCH RESEND] driver core: export device_is_bound() to fix build failure

When CONFIG_MXC_CLK_SCU is configured as 'm' the build fails as it
is unable to find device_is_bound(). The error being:
ERROR: modpost: "device_is_bound" [drivers/clk/imx/clk-imx-scu.ko]
	undefined!

Export the symbol so that the module finds it.

Fixes: 77d8f3068c63 ("clk: imx: scu: add two cells binding support")
