This patch series include a few more NPCM7XX devices including

- Analog Digital Converter (ADC)
- Pulse Width Modulation (PWM)

We also modified the CLK module to generate clock values using qdev_clock.
These clocks are used to determine various clocks in NPCM7XX devices.

Thank you for your review.

Changes since v4:
- Use clock_ticks_to_ns to compute clock time in nanoseconds.
    (Didn't apply to PWM patch since it requires a frequency as output.)
- Removed reset_timer and resets immediately in ADC patch.
- Removed "qemu/osdep.h" from headers and include them in .c files.
- Use REG32 for register fields.
- Fix a g_assert that a guest can trigger with incorrect input.

Changes since v3:
- Use type casting instead of accessing parent object in all devices.

Changes since v2:
- Split PWM test into a separate patch in the patch set
- Add trace events for PWM's update_freq/update_duty
- Add trace events for ioread/iowrite in ADC and PWM
- Use timer_get_ns in hw/timer/npcm7xx_timer.c
- Update commit message in ADC/PWM to mention qom-get/set method for usage
- Fix typos

Changes since v1:
- We removed the IPMI and KCS related code from this patch set.

Applied to target-arm.next with a fixup to the ADC patch for
the missing trace.h file.
