c79aa350ea hw/arm/npcm7xx: Declare QOM macros using OBJECT_DECLARE_SIMPLE_TYPE()
NPCM7XX models have been commited after the conversion from
commit 8063396bf3 ("Use OBJECT_DECLARE_SIMPLE_TYPE when possible").
Manually convert them.

0be12dc76a hw/timer: Refactor NPCM7XX Timer to use CLK clock
This patch makes NPCM7XX Timer to use a the timer clock generated by the
CLK module instead of the magic number TIMER_REF_HZ.

bcda710f6c hw/misc: Add clock converter in NPCM7XX CLK module
This patch allows NPCM7XX CLK module to compute clocks that are used by
other NPCM7XX modules.

Add a new struct NPCM7xxClockConverterState which represents a
single converter.  Each clock converter in CLK module represents one
converter in NPCM7XX CLK Module(PLL, SEL or Divider). Each converter
takes one or more input clocks and converts them into one output clock.
They form a clock hierarchy in the CLK module and are responsible for
outputing clocks for various other modules in an NPCM7XX SoC.

Each converter has a function pointer called "convert" which represents
the unique logic for that converter.

The clock contains two initialization information: ConverterInitInfo and
ConverterConnectionInfo. They represent the vertices and edges in the
clock diagram respectively.

7d378ed6e3 hw/timer: Adding watchdog for NPCM7XX Timer.
The watchdog is part of NPCM7XX's timer module. Its behavior is
controlled by the WTCR register in the timer.

When enabled, the watchdog issues an interrupt signal after a pre-set
amount of cycles, and issues a reset signal shortly after that.

e331f79eb8 hw/misc: Add NPCM7xx Clock Controller device model
Enough functionality to boot the Linux kernel has been implemented. This
includes:

  - Correct power-on reset values so the various clock rates can be
    accurately calculated.
  - Clock enables stick around when written.

In addition, a best effort attempt to implement SECCNT and CNTR25M was
made even though I don't think the kernel needs them.
