Subject: hw/misc: Support NPCM8XX CLK Module Registers
NPCM8XX adds a few new registers and have a different set of reset
values to the CLK modules. This patch supports them.
This patch doesn't support the new clock values generated by these
registers. Currently no modules use these new clock values so they
are not necessary at this point.
Implementation of these clocks might be required when implementing
these modules.
