[PATCH v2 0/3] regulator: handle regulator late cleanup race with PM suspend

The regulator_init_complete_work fires ~30s after boot to disable
unused regulators via I2C. When this work races with PM suspend, the
I2C adapter may already be suspended, causing a -ESHUTDOWN warning
dump.

This series addresses the race and adds proper suspend power
management for unused LDO regulators.

Changes in v2:
- trim the oversized register dump from the backtrace in the commit
  message, keeping only the relevant call trace.
- rename the callback to pfuze100_ldo_set_suspend_disable since it is
  only wired into the LDO ops.
- use the per-regulator stby_reg/stby_mask instead of a hardcoded
  VGENxSTBY/VGENxLPWR bit.
- clarify that the change targets suspend power reduction and remove the
  redundant race-condition wording so the commit message is clearer.
- Link to v1: https://patch.msgid.link/[email protected]
