Merge tag 'u-boot-imx-next-20240902' of https://gitlab.denx.de/u-boot/custodians/u-boot-imx into next

CI: https://source.denx.de/u-boot/custodians/u-boot-imx/-/pipelines/22211

- Enable SPI NOR flash support and MTD partitions for phycore_imx8mp.
- Convert mx6slevk to OF_UPSTREAM and watchdog DM.
- Cleanup some mx5/mx6 USB options.
- Make PLL settings configurable at board level.
- Set CONFIG_SPL_LOAD_FIT_ADDRESS for verdin-imx8m/p.
- Make the mxc-gpio reading state of GPIO pins in output mode to be
  consistent with the Linux kernel.
- Add HUK derivation support for ELE AHAB.
