[PATCH] clk: imx: fix compile testing imxrt1050

[PATCH] clk: imx: fix compile testing imxrt1050

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Randconfig testing revealed multiple issues with this driver:

ERROR: modpost: missing MODULE_LICENSE() in drivers/clk/imx/clk-imxrt1050.o
ERROR: modpost: "imx_clk_hw_pllv3" [drivers/clk/imx/clk-imxrt1050.ko] undefined!
ERROR: modpost: "imx_clk_hw_pfd" [drivers/clk/imx/clk-imxrt1050.ko] undefined!

Export the necessary symbols from the core clk driver and add the
license and author tags. To find this type of problem more easily
in the future, also enable building on other platforms, as we do for
the other i.MX clk drivers.

Not sure what COMPILE_TEST is but,

Sorry about the issues introduced.

The idea is that you can enable the driver to be built in
allmodconfig or randconfig regardless of the architecture,
to see any compiler-time warnings creeping up without
having to build an imxrt specific kernel.

Applied to clk-next
