ieee802154: ca8210: Use proper setters and getters for bitwise types

[ Upstream commit 169b2262205836a5d1213ff44dca2962276bece1 ]

Sparse complains that the driver doesn't respect the bitwise types:

drivers/net/ieee802154/ca8210.c:1796:27: warning: incorrect type in assignment (different base types)
drivers/net/ieee802154/ca8210.c:1796:27:    expected restricted __le16 [addressable] [assigned] [usertype] pan_id

Use proper setters and getters for bitwise types.

Note, in accordance with [1] the protocol is little endian.
