atheros: add support for linux kernel v3.8
This builds and boots.
Because of the function pointer indirection (e.g. mtd_info's read
function pointer is assigned to spiflash_read), it is difficult for me
to understand where the calls are coming from (could be anywhere,
conditionally pointing at spiflash versions), so I punted and used the
renamed function pointers (_erase, _read, _write). If someone knows
better what to do, please fix.
Cleaned up other sundry kernel tracking issues like get_phy_id and
__devinit,etc.
[juhosg: don't switch to that yet]
