Add support for SAMA7D65

From: Ryan Wanner <[email protected]>

This series adds support for the SAMA7D65 SoC.

V2 of this series [1].
V3 of this series [2].
V4 of this series [4].
V5 of this series [6].

For the pinctrl and pit64 timers those will have DTB warnings due to those bindings not being in the .yaml format.

Changes v1->v2:
- V1 set was sent incorrectly as multiple seprate patches v2 took all those patches and put them in 1 thread.

Changes v2->v3:
- Correct the patch order to follow correct practice.
- Correct flexcom dt-binding commit messge to reflect the changes in the coding style.
- Add missing SoB tags to patches.
- Moved export clocks to DT patch to be included with the clock binding patch.
- Separate Kconfig changes and defconfig changes into different patches and removed unused Kconfig params.
- Correct confusing SoB and Co-developed chain.
- Removed unsued nodes in DTSI file and sorted includes alphanumerically.
- Fix incorrect dts formatting.
- Separate dts and pinmux changes into two patches.
- Combine PLL and MCK changes into core clock driver patch.
- Correct formatting in main clock driver.
- MMC dt-binding changes are applied for next so have been removed from the set [3].

Changes v3->v4:
- Collect all tags from maintainers.
- Correct compile error on 11/13 and correct location of vendor specific properties.
- Add USB and UTMI selections to 12/13 to prevent compile errors due to functions in the clock driver that use the USB clock system.
- Add "microchip,sama7g5-pinctrl" compatible string as a fall back in 9/13.
- Add missing kfree() to 8/13 to correctly handle error case.
- Replace bad spacing with correct tab formatting on 7/13.

Changes from v4->v5:
- Remove patches that have been applied [5].
- Update pinctrl dt-binding to use fallback formatting.

Changes from v5->v6:
- Remove patches that have been applied [6].
- Correct incorrect spacing formatting on pinctrl dt-binding.
- Reintroduce flexcom to the thread since it was removed due to an error in collecting applied patches.

Note:
- For the SDHCI DTB error that patch has been removed do to it being applied see [3].
- There are DTB errors on microchip,sama7d65-pit64b and microchip,sama7d65-pinctrl, this is due to those bindings being .txt files.
