Merge tag 'efi-next-03072025' of https://source.denx.de/u-boot/custodians/u-boot-tpm into next

Sughosh added EFI HTTP(s) support into our eficonfig application. Up to
now we could only enable that via our efidebug command. Users now get that
option on the eficonfig menu.

Javier implemented support for the EFI_PARTITION_INFO_PROTOCOL,
to provide cached partition information for GPT partition types.
The protocol describes legacy MBR partition types, but that's for backward
compatibility and not implemented by this series.
The protocol is needed by [0], an implementation of a UEFI based A/B boot
protocol for the root filesystem.

Paul added support for EFI_DEBUG_IMAGE_INFO_TABLE. This is part of the EFI
spec and is defining a debug protocol that Google currently uses to debug
their Generic Bootloader project [1][2], using EFI to load Android.
Heinrich contributed a test EFI application for it as well.
The efi_realloc() function he added will realloc any type of memory to
BootServicesData, but keeping in mind the new protocol is the only consumer
he will fix that on a followup patch.

Finally another round of smatch fixes from Andrew cleans up coding errors.

The CI https://source.denx.de/u-boot/custodians/u-boot-tpm/-/pipelines/26935
seems happy
