Merge tag 'u-boot-at91-fixes-2023.10-a' of https://source.denx.de/u-boot/custodians/u-boot-at91
First set of u-boot-atmel fixes for the 2023.07 cycle: This small fixes set includes the LTO configs for the boards that had the SPL size up to the limit (sama5d2-based), such that more code can be added. It also includes a fix for mmc non-removable.
