[PATCH v3 0/5] Add partition type GUID support for environment

[Balaji Selvanathan]

This series adds support for locating partitions using GPT partition
type GUID instead of unique partition UUID. This enables the saveenv
command to work with partitions identified by their type rather than
unique identifiers, providing flexibility for systems where partition
UUIDs may vary across devices but types remain constant.

Patch 1 adds part_get_info_by_type_guid() function support
Patch 2 adds scsi_get_blk_by_type_guid() function support
Patch 3 adds support for partition type GUID based environment
Patch 4 enables partition type GUID configs for QCM6490 and QCS615
Patch 5 adds unit test for the partition type GUID lookup functionality

Changes in v3:
- Addressed minor corrections in Patch 1 in part_get_info_by_type_guid function
- Refactor env_scsi_get_part and env_scsi_load functions based
  on the choice configs in Patch 3
- Add unit test for the partition type GUID lookup functionality in Patch 5
- Link to v2: https://lore.kernel.org/u-boot/20260109070912.4106466-1-balaji.selvanathan@oss.qualcomm.com/

Changes in v2:
- Compute blk_find_max_devnum(UCLASS_SCSI) only once in scsi_get_blk_by_type_guid()
- Introduce a Kconfig choice config to select between UUID-based
and type GUID-based partition lookup methods.
- Enable above new config in qcom_qcs615_defconfig and qcm6490_defconfig
- Link to v1: https://lore.kernel.org/u-boot/20260108064947.3237361-1-balaji.selvanathan@oss.qualcomm.com/
