Merge tag 'u-boot-imx-next-20260228' of https://gitlab.denx.de/u-boot/custodians/u-boot-imx into nextnext

CI: https://source.denx.de/u-boot/custodians/u-boot-imx/-/pipelines/29404

- Miscelanous improvements for Siemens Capricorn board.
- Convert i.MX6 IPUv3 driver to use clock framework.
- Skip voltage switching for fixed 1.8V regulator on fsl_esdhc_imx.
- Support printing imx8m pinmux.
- Enter fastboot on USB boot by default on phycore-imx93.
- Use arch override for env_get_location() on imx95.
