ath10k: add memory dump debugfs interface
Add mem_val debugfs file for dumping the firmware (target) memory and also for
writing to the memory. The firmware memory is accessed through one file which
uses position of the file as the firmware memory address. For example, with dd
use skip parameter for the address.
Beucase target memory width is 32 bits it's strongly recommended to use
blocksize divisable with 4 when using this interface. For example, when using
dd use bs=4 to set the block size to 4 and remember to divide both count and
skip values with four.

returned with status "Command Disallowed" (0x0C) the flag
HCI_CONN_RSWITCH_PEND remains set. No further role switches are
possible as this flag prevents us from sending any new HCI Switch Role
requests and the only way to clear it is to receive a valid
HCI Event Switch Role.
This patch clears the flag if command was rejected.

mac802154: use IEEE802154_EXTENDED_ADDR_LEN
This patch removes the af_ieee802154 defines and use the
IEEE802154_EXTENDED_ADDR_LEN. We should do this everywhere in the
802.15.4 subsystem because af_ieee802154 should be normally an uapi
header.

at86rf230: add force slotted operation bit
This patch adds a force setting of slotted operation bit. The atben
chips sometimes set these bit. The reason is unknown. Nevertheless we
don't support slotted operation so we set this bit now force while
probing.

mac802154: add support for perm_extended_addr
This patch adding support for a perm extended address. This is useful
when a device supports an eeprom with a programmed static extended address.
If a device doesn't support such eeprom or serial registers then the
driver should generate a random extended address.

This patch cleanups the ieee802154_be64_to_le64 to have a similar
function like ieee802154_le64_to_be64 only with switched source and
destionation types.
