netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328

Browse Source 
The drivers were touching net queue before it has been started, so
without this patch, the drivers will potentially WARN at
net/core/dev.c:1328.

I don't have the hardware for the drivers below, so this patch is
untested, and thus should be carefully peer reviewed.

tc35815.c
au1000_eth.c
bfin_mac.c
macb.c
^ The four drivers are using phylib, they're calling netif_start_queue()
in open() callback. So trivially remove netif_tx_schedule_all().
Phylib will handle netif_carrier_*().

cpmac.c
fec_mpc52xx.c
fs_enet/fs_enet-main.c
sh_eth.c
^ The same as above, but these were also needlessly calling
netif_carrier_*() functions. So removed queue calls and also remove
carrier calls, since phylib will handle it. fs_enet-main.c also didn't
call netif_start_queue() at open(), this is fixed now.
