Place for gathering FW dump template has been moved to the FW restart path
so that the driver can check if a newer FW version is available and in that case
it replaces the existing FW dump template with the newer template.

64-bit stats in be2net are written/read as follows using the stats-sync
interface for safe access in 32-bit archs:

64-bit 		sync			writer			reader
stats
------------------------------------------------------------------------------
tx_stats	tx_stats->sync		be_xmit			be_get_stats64,
								ethtool
tx-compl	tx_stats->sync_compl	tx-compl-processing	ethtool
rx-stats	rx_stats->sync		rx-compl-processing	be_get_stats64,

In preparation for 64-bit stats interface, the following cleanups help
streamline the code:
1) made some more rx/tx stats stored by driver 64 bit
2) made some HW stas (err/drop counters) stored in be_drv_stats 32 bit to
   keep the code simple as BE provides 32-bit counters only.
3) removed duplication of netdev stats in ethtool
4) removed some un-necessary stats and fixed some names

In drivers/mfd/tps65910.c:tps65910_i2c_probe() there's potential for a
tiny optimization.

We assign to init_data->irq and init_data->irq_base long before we
need them, and there are two potential exits from the function before
they are needed.

Moving the assignments below these two potential exits means we
completely avoid doing them in these two (failure) cases.
