Richard Cochran 74d23cc704 time: move the timecounter/cyclecounter code into its own file.
The timecounter code has almost nothing to do with the clocksource
code. Let it live in its own file. This will help isolate the
timecounter users from the clocksource users in the source tree.

Joe Perches 95f7f1519d ti: Remove extern from function prototypes
There are a mix of function prototypes with and without extern
in the kernel sources.  Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler.  Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

Richard Cochran cbc44dbe1f cpts: fix build error by removing useless code.
The cpts driver tries to obtain the input clock frequency by calling the
clock's internal 'recalc' method. Since <plat/clock.h> has been removed,
this code can no longer compile.

However, the driver never makes use of the frequency value, so this patch
fixes the issue by removing the offending code altogether.

Richard Cochran 87c0e764d4 cpts: introduce time stamping code and a PTP hardware clock.
This patch adds a driver for the CPTS that offers time
stamping and a PTP hardware clock. Because some of the
CPTS hardware variants (like the am335x) do not support
frequency adjustment, we have implemented this in software
by changing the multiplication factor of the timecounter.
