2015-06-16at86rf230: fix phy settings while sleepingAlexander Aring1-20/+68
While in sleep state then we can't access the at86rf2xx registers. This patch checks if the transceiver is in sleep state before sending spi messages via regmap. Regmap is used on every driver ops callback except for receive and xmit handling, but while receive and xmit handling the phy should not be inside the sleep state.

This patch introduce a flag property for the wpan phy structure. The current flag settings in ieee802154_hw are accessable in mac802154 layer only which is okay for flags which indicates MAC handling which are done by phy. For real PHY layer settings like cca mode, transmit power, cca energy detection level. The difference between these flags are that the MAC handling flags are only handled in mac802154/HardMac layer e.g. on an interface up. The phy settings are direct netlink calls from nl802154 into the driver layer and the nl802154 need to have a chance to check if the driver supports this handling before sending to the next layer. We also check now on PHY flags while dumping and setting pib attributes. In comparing with MIB attributes the 802.15.4 gives us an default value which we assume when a transceiver implement less functionality. In case of MIB settings the nl802154 layer doesn't need to check on the ieee802154_hw flags then.
