IIO fixes for elements queued for 3.6 merge window.

3 types of fix here.
 
 1) Incorrect pointer casting via phys_addr_t which causes
    trouble on some architectures.
 2) request_irq and free_irq dev_id parameters not matching.
 3) Inconsistencies in client_data for some i2c devices
 (writing one pointer and expecting another later).
