[PATCH V7 0/3] scsi: ufs-qcom: Enable Hibern8, MCQ, and Testbus registers Dump

[Manish Pandey <quic_mapa@quicinc.com>]

Adding support to enhance the debugging capabilities of the Qualcomm UFS
Host Controller, including HW and SW Hibern8 counts, MCQ registers, and
testbus registers dump.
---
Changes in v7:
- Addressed Bart's comment and used table-based approach to for ufs_qcom_dump_regs().
Changes in v6:
- Added ufs_qcom_dump_regs() API for MCQ dump due, as SoC vendors explicitly
  allocate MCQ resource.
Changes in v5:
- Addressed Mani's comment and used cond_resched() instead of usleep().
Changes in v4:
- Addressed Mani's comment and used kmalloc_array() for testbus mem allocation.
- Removed usleep_range from ufs_qcom_dump_testbus.
- Updated commit text.
Changes in v3:
- Addressed Bart's comment and Annotated the 'testbus' declaration with __free.
- Converted the switch-statements into an array lookup.
- Introduced struct testbus_info{} for handling testbus switch-statements to an array lookup.
Changes in v2:
- Rebased patchsets.
- Link to v1: https://lore.kernel.org/linux-arm-msm/20241025055054.23170-1-quic_mapa@quicinc.com/
