This patch fixes a bug in which the timer routine synchronized
against the ethtool-triggered statistics updates with spin_lock_bh().
A timer function is itself a bottom-half, so this should be
spin_lock().

This patch fixes error in the setting of the hw statistics
module base for K2HK platform. In K2HK although there are
4 hw statistics modules, but only 2 are visible at a time.
Thus when setting up the pointers to the base of the
corresponding hw statistics modules, modules 0 and 2 should
point to one base, while modules 1 and 3 should point to the
other.

The CPSW driver keeps internally some, but not all, of
the statistics available in the hw statistics modules. Furthermore,
some of the locations in the hw statistics modules are reserved and
contain no useful information. Prior to this patch, the driver
allocates memory of the size of the the whole hw statistics modules,
instead of the size of statistics-entries-interested-in (i.e. et_stats),
for internal storage. This patch fixes that.

Different Keystone2 platforms have different number and
layouts of hw statistics modules. This patch consolidates
the statistics processing of different Keystone2 platforms
for easy maintenance.

In certain applications it's beneficial to allow the CPSW h/w
stats counters to continue to increment even while the kernel
polls them. This patch implements this behavior for both 1G
and 10G ethernet subsystem modules.
