- Platform data is treated as const and not modified in driver.
- Driver specific data is stored and used from a new structure.
- Remove support for older firmware version of XMM modem (<1130).
- Shortening of names for compliance and to fit in 80 characters.
- Organize irq function to reduce indentation.

Check the state machine before poweron the modem by device
attribute change routine. Maintain the state machine to
avoid crash after writing state change to
/sys/devices/platform/baseband_xmm_power/xmm_onoff
Also cancel workqueue at module unload to avoid
possible crash.
