ata/drivers/ahci_imx: Switch to new of thermal API

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.

Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

sata_ahci_read_temperature() is used by sata_ahci_show_temp() also.

So in order to change the function prototype for the get_temp ops which
does not take a void* but a thermal_zone_device* structure, this
function wraps the call.
