System timer changes for omaps for v5.8 merge window

This series of changes finally gets the legacy omap dual-mode timer and
 32k counter system timer updated to use drivers/clocksource and device
 tree data. And we can now remove the unused legacy platform data.
 
 These changes are based on an immutable clocksource branch set up by
 Daniel Lezcano.

* tag 'omap-for-v5.8/timer-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  bus: ti-sysc: Timers no longer need legacy quirk handling
  ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter
  ARM: dts: Configure system timers for omap2
  ARM: dts: Configure system timers for ti81xx
  ARM: dts: Configure system timers for omap3
  ARM: dts: Configure system timers for omap5 and dra7
  ARM: dts: Configure system timers for omap4
  ARM: dts: Configure system timers for am437x
  ARM: dts: Configure system timers for am335x
  ARM: OMAP2+: Add omap_init_time_of()
  bus: ti-sysc: Ignore timer12 on secure omap3
  clk: ti: dm816: enable sysclk6_ck on init
  clocksource/drivers/timer-ti-dm: Fix warning for set but not used
  clocksource/drivers/timer-ti-dm: Add clockevent and clocksource support
  clocksource/drivers/timer-ti-32k: Add support for initializing directly
