Michael Hennerich 8f1878a182 net: ieee802154: adf7242: Rework IRQ and packet handling
* Stop unconditionally polling for RC_STATUS_PHY_RDY at the entry of
the threaded IRQ handler. Once IRQ_RX_PKT_RCVD is received we can
read immediately the packet from the buffer. However we still need
to wait afterwards for RC_STATUS_PHY_RDY, to make sure that the
ACK (in case requested) was processed and send out by the
Radio Controller, before we issue the next CMD_RC_RX.
This significantly reduces the overall time spend in the threaded
IRQ handler.

 * Avoid raise condition between xmit and coincident packet reception,
by disabling the IRQ and clearing the IRQ status upon xmit entry.

 * Introduce helper functions adf7242_clear_irqstat() and adf7242_cmd_rx()
