This implements basic driver to utilize the I3C IP block
on NPCX.
1. I3C mode: Main controller mode only.
2. Transfer: Support SDR only.
3. IBI: Support Hot-Join, IBI(MDB).
Controller request is not supported.
4. Support 3 I3C modules:
I3C1(3.3V), I3C2(1.8V, espi mode), (I3C3 1.8V or 3.3V)

Nuvoton NPCX chips have reset registers which allow to reset the
peripheral hardware modules. This commit adds the support by
implementing the reset driver. Note that only the reset_line_toggle API
is supported because of the nature of the reset controller's design.

The commit fixes the SHA driver because the ROM API has the following
changes from ES to QS chip:
1. base addres: from 0x13c -> 0x148
2. required SHA context buffer size : from 228 -> 240 bytes
This change also adds a check for the pre-allocated buffer size of the
SHA context when the driver initiliazes.

The shi module in npcx4 supports the enhanced buffer mode.
Add a new compatible string "nuvoton,npcx-shi-enhanced" for it.
Then the shi driver can determine if it should use the enhanced buffer
mode based on the compatiable string.

The pre-alloacted size of the buffer for the SHA ROM API code increases
in npcx4 chip. This commit adds a new property context-buffer-size to
sha0 DT node in npcx9 and npcx4 separately. The driver can pre-allocate
buffer with the correct size based on the property.

Add multi-device support in npcx adc driver since there is more than one
adc module in npcx4 series. And each adc's reference voltage might be
different, this CL introduces the `vref-mv` prop. to select its own
reference voltage.

This CL introduces new clock architectures in npcx4 series and wraps
clock configurations of different series by device tree files.
For example, the PWDWN_CTLx reg initialization relies on `pwdwn-ctl-val`
prop of pcc DT node now.
