Add clock driver support for i.MXRT1050.

Signed-off-by: Jesse Taube <Mr.Bossman075@gmail.com>
Suggested-by: Giulio Benetti <giulio.benetti@benettiengineering.com>
---
V1->V2:
* Kconfig: Add new line
* clk-imxrt.c: Remove unused const
* clk-imxrt.c: Remove set parents
* clk-imxrt.c: Use fsl,imxrt-anatop for anatop base address
V2->V3:
* Remove unused ANATOP_BASE_ADDR
* Move to hw API
* Add GPT's own clock
* Add SEMC clocks to set muxing to CRITICAL
V3->V4:
* Rename clk-imxrt.c to clk-imxrt1050.c
* Rename CONFIG_CLK_IMXRT to CONFIG_CLK_IMXRT1050
* Make CONFIG_CLK_IMXRT1050 selectable
V4->V5:
* Move to platform driver

Name here should be: "imxrt1050-ccm". Drop the "fsl,".

Look at the other imx clock drivers::
	$ git grep "\.name = \"" drivers/clk/imx/clk-imx*
	drivers/clk/imx/clk-imx8mm.c:           .name = "imx8mm-ccm",

	drivers/clk/imx/clk-imx8mp.c:           .name = "imx8mp-ccm",
	drivers/clk/imx/clk-imx8mq.c:           .name = "imx8mq-ccm",
