acpi_handle_info() uses the ACPI path to the handle as prefix for messages
e.g. : "\_SB_.I2C2.CAM8".
This makes it hard for users to figure out which csi2-bridge messages
belong to which sensor since the actual sensor drivers uses the ACPI
device name (typically "HID:00") for logging.
Extend the acpi_handle_info() (and err and warn) logging to also log
the device name to make it easier to match csi2-bridge messages with
sensor driver log messages.
