Subject: [PATCH v2] soc: qcom: mention intentionally broken module autoloading

Qualcomm PMIC ChargerPD ULOG and RPM Master Statistics drivers are
solely for debugging purposes and should not be autoloaded as modules.
Add comments to annotate missing MODULE_DEVICE_TABLE.

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

Changes in v2:
1. Rework, drop MODULE_DEVICE_TABLE, add comment.
