[PATCH v4 0/3] hw/timer: add DesignWare APB timer

Add a generic DesignWare APB timer device model, and wire it
up for the K230 machine with num-timers=6 and a 6.25 MHz clock.

Changes since v3 (address review comments from Philippe Mathieu-Daude):
- Drop Clock framework mention from the commit message
- Cover the device in MAINTAINERS (device files in patch 1/3,
  test file in patch 3/3)
- Move trace calls to function entry
- Drop the addr mask; the MMIO region stays at 0x100 (the IP
  register implementation range; the SoC aperture is board-level)
- Hard-code comp-version (0x3231312A, "211*", IP component version)
- Use the Resettable API (phases.hold) instead of legacy reset
- Add unrealize to free per-channel ptimers
- Keep register offsets and bit definitions in the C file
- Drop private/public comments in the header
- Move K230 timer macros into k230.c
