ACPI: button: Clean up adding and removing lid procfs interface

The procfs interface is only used with lid devices which only becomes
clear after looking into the function bodies of acpi_button_add_fs()
and acpi_button_remove_fs().  Moreover, the only error code returned
by the former of these functions is -ENODEV, so the ret local variable
in it is redundant, and the return type of the latter one can be changed
to void.

Accordingly, rename these functions to acpi_button_add_fs() and
acpi_button_remove_fs(), respectively, move the button->type checks
against ACPI_BUTTON_TYPE_LID from them to their callers, and make
code simplifications as per the above.

No intentional functional impact.
