clk: imx: imx8mm: fix a53 cpu clock

The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root
signoff timing is 1Ghz, however the A53 core which sources from CCM
root could run above 1GHz which voilates the CCM.

There is a CORE_SEL slice before A53 core, we need configure the
CORE_SEL slice source from ARM PLL, not A53 CCM clk root.

The A53 CCM clk root should only be used when need to change ARM PLL
frequency.

Add arm_a53_core clk that could source from arm_a53_div and arm_pll_out.
Configure a53 ccm root sources from 800MHz sys pll
Configure a53 core sources from arm_pll_out
Mark arm_a53_core as critical clock

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
"This merge window we have one small clk provider API in the core
framework and then a bunch of driver updates and a handful of new
drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
high up there because of all the clk data introcued by new drivers.
The Nvidia Tegra driver had a lot of work done this cycle too to
support suspend/resume and memory controllers. And the OMAP clk driver
got proper clk and reset handling in place.

Rounding out the patches are various updates to remove unused data,
mark things static, correct incorrect data in drivers, etc. All the
little things that improve drivers and maintain code health. I will
point out that there's a patch in here for the GPIO clk driver, that
almost nobody uses, which changes behavior and causes clk_set_rate()
to try to change the GPIO gate clk's parent. Other than that things
are fairly well SoC specific here.

Core:
- Add a clk provider API to get current parent index
- Plug a memory leak in clk_unregister() path

New Drivers:
- CGU in Ingenix X1000
- Bitmain BM1880 clks
- Qualcomm MSM8998 GPU clk controllers
- Qualcomm SC7180 GCC and RPMH clk controllers
- Qualcomm QCS404 Q6SSTOP clk controllers
- Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
- Add support for the Renesas RZ/G2N (r8a774b1) SoC
- Add Tegra20/30 External Memory Clock (EMC) support

Updates:
- Make gpio gate clks propagate rate setting up to parent
- Prepare Armada 3700 for suspend to RAM by moving PCIe
suspend/resume priority
- Drop unused variables, enums, etc. in various clk drivers
- Convert various drivers to use devm_platform_ioremap_resource()
- Use struct_size() some more in various clk drivers
- Improve Rockchip px30 clk tree
- Add suspend/resume support to Tegra210 clk driver
- Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
- Allwinner DT exports and H6 clk tree fixes
- Proper clk and reset handling for OMAP SoCs
- Revamped TI divider clk to clamp max divider
- Make 1443X/1416X PLL clock structure common for reusing among i.MX8
SoCs
- Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
- Add VIDEO2_PLL clock for imx8mq
- Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
- Add sm1 support in the Amlogic audio clock controller
- Switch some clocks on R-Car Gen2/3 to .determine_rate()
- Remove Renesas R-Car Gen2 legacy DT clock support
- Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
- Improve Renesas R-Car Gen3 SD clock handling
- Add rate table for Samsung exynos542x GPU and VPLL clks
- Fix potential CPU performance degradation after system
suspend/resume cycle on exynos542x SoCs"

On imx8mm there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2

one) is currently defined and it's incorrectly set as the parent of all
