Remove conservation mode reporting since it is already reported via the
appropriate device attribute, and its state can be deduced from the value
of GBMD. Add the return value of the GBMD and HALS ACPI methods to the
output. Change the return value to -ENODATA when the driver-specific data
is not available. Use seq_puts() where possible.
