platform/x86: ideapad-laptop: rework and create new ACPI helpers

Browse source

Create dedicated helper functions for accessing the main ACPI methods:
GBMD, SMBC, HALS, SALS; and utilize them. Use `unsigned long` consistently
in every ACPI helper wherever possible. Change names to better express
purpose. Do not assign values to output parameters in case of failure.
