Add support for SAMA7D65

From: Ryan Wanner <Ryan.Wanner@microchip.com>

This series adds support for the SAMA7D65 SoC.

V2 of this series [1].
V3 of this series [2].

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.
