Passing pdev in fec_ptp_init() is enough, since we can get ndev locally.

Use a more current logging message style.
Convert the printks where a struct net_device is available to
netdev_<level>. Convert the other printks to pr_<level> and
add pr_fmt where appropriate.

Currently when booting a mx6 device we get the following on boot:
registered PHC device on eth%d
Fix it by printing the network device name only after it gets registered, so
that the following can be read now:
fec 2188000.ethernet eth0: registered PHC device 0

fec_ptp.ko can't run individually
rename fec.c to fec_main.c
Build fec.o and fec_ptp.o into one fec.ko
Remove unnessary EXPORT_SYMBOL in fec_ptp

Since commit ff43da86c69 (NET: FEC: dynamtic check DMA desc buff type) the
following build error happens when CONFIG_FEC=m
ERROR: "fec_ptp_init" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_ioctl" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_start_cyclecounter" [drivers/net/ethernet/freescale/fec.ko] undefined!
Fix it by exporting the required fec_ptp symbols.

=========================================================
[ INFO: possible irq lock inversion dependency detected ]
3.8.0-rc5+ #82 Not tainted
---------------------------------------------------------
swapper/0/0 just changed the state of lock:
(&(&fep->hw_lock)->rlock){..-...}, at: [<8034e2f8>] fec_enet_start_xmit+0x48/0x 2cc
but this lock took another, SOFTIRQ-unsafe lock in the past:
(prepare_lock){+.+.+.}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:
CPU0 CPU1
---- ----
lock(prepare_lock);
local_irq_disable()
lock(&(&fep->hw_lock)->rlock);
lock(prepare_lock);
<Interrupt>
lock(&(&fep->hw_lock)->rlock);

move below calculate out of spin lock section
diff = fep->cc.mult;
diff *= ppb;
diff = div_u64(diff, 1000000000ULL);
diff is local variable and not neccesary in spin lock

This patch adds a driver for the FEC(MX6) that offers time
stamping and a PTP haderware clock. Because FEC\ENET(MX6)
hardware frequency adjustment is complex, we have implemented
this in software by changing the multiplication factor of the
timecounter.
