[PATCH v1 2/5] ACPI: battery: Clean up printing messages

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Replace the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances
in battery.c with acpi_handle_debug() and acpi_handle_info() calls,
respectively, drop the _COMPONENT and ACPI_MODULE_NAME() definitions
that are not used any more, drop the no longer needed
ACPI_BATTERY_COMPONENT definition from the headers and update the
documentation accordingly.

While at it, update the pr_fmt() definition and drop the unneeded
PREFIX sybmbol definition from battery.c.
