Michał Kępień 32c28f1f43 platform/x86: fujitsu-laptop: do not evaluate ACPI _INI methods
acpi_ns_initialize_devices(), which is called during system-wide ACPI
initialization, already detects and calls all _INI methods belonging to
objects present in ACPI tables.  There is no need to call these methods
again every time the module is loaded because they only initialize
status flags and hotkey-related variables; status flags are effectively
constants, hotkey-related variables may be assigned non-zero values
before acpi_fujitsu_laptop_add() is called, but that does not really
matter as we drain the scancodes queued in the firmware's ring buffer
before doing anything else.

Remove sections of code which invoke and check evaluation status of the
_INI methods belonging to the ACPI devices handled by the driver.
