clk: imx: fix compile testing imxrt1050

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.
