at86rf230: add support for calibration timeout
This patch adds a handling for calibration if we are 5 minutes in PLL state. I first tried to implement the calibration functionality in TX_ON state via register values CF_START and DCU_START, but this occurs a one second delay at each calibration time. An another solution to start a calibration is to switch from TRX_OFF state into TX_ON, then a calibration is done automatically by transceiver. This method will be used in this patch, after each transmit of a frame we check with jiffies if the PLL is set 5 minutes without doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case would be a transceiver in receiving mode only, but this is under normal operation very unlikely.
