Add named defines for all registers and bits in timer-vt8500.
Move the system events timer from channel 0 to channel 1 when enough
information is provided by the device tree (i.e. more than one IRQ).
Use channel 0 for the system watchdog

Changes in v3:
- Dropped the DTS patch already applied by Krzysztof
- Rebased onto v6.15-rc5 as requested by Daniel
- Split out the watchdog code into a dedicated platform driver, like
  timer-gxp does (thanks Daniel)
- Link to v2: https://lore.kernel.org/r/20250507-vt8500-timer-updates-v2-0-65e5d1b0855e@gmail.com

Changes in v2:
- Included the previously reviewed binding change that is directly related
  to this series as the first patch here (thanks Krzysztof)
- Created a separate config symbol for the watchdog function to let users
  build a kernel without forcing watchdog functionality upon them
  (thanks Krzysztof)
- Link to the previous binding submission: https://lore.kernel.org/all/20250506-via_vt8500_timer_binding-v3-1-88450907503f@gmail.com/
- Link to v1: https://lore.kernel.org/r/20250507-vt8500-timer-updates-v1-0-6b76f7f340a6@gmail.com
