The DSDT also reference a WIMAX device, which is not present on this model. This patch adds two new files: wwan and wimax to control WWAN and WIMAX devices. It does not use rfkill, because like WLED and BLED, we don't know yet that the two ACPI functions will always control the radio, they may control only the leds on some hardware. We may add rfkill switchs later.

This allows keeping a cleaner interface within the sysfs guidelines. The ABI documentation was updated too.
