[ Upstream commit 8b5bf64c89c7100c921bd807ba39b2eb003061ab ]
Smatch reports:
drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe()
warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516.
timer_baseaddr may have the problem of not being released after use,
I replaced it with the devm_of_iomap() function and added the clk_put()
function to cleanup the "clk_ce" and "clk_cs".

If clk_notifier_register() failed, ttc_setup_clockevent() will return
without freeing 'ttcce', which will leak memory.

Currently TTC driver is TIMER_OF_DECLARE type driver. Because of
that, TTC driver may be initialized before other clock drivers. If
TTC driver is dependent on that clock driver then initialization of
TTC driver will failed.
So use TTC driver as platform driver instead of using
TIMER_OF_DECLARE.

In order to make some housekeeping in the directory, this patch renames
drivers to the timer-* format in order to unify their names.
There is no functional changes.
