Create the pinmux phandle to the SHI driver node in the
devicetree. When the pinmux_pin_set function in
cros_shi_ite_init can refer to the setting of phandle.
It is more flexible to use.

In NPCX7mnFA, the old SHI module and the new SHI module co-exist in this
chip. We need to set DEVALTF.bit7 to enable the new version of the SHI
module. In the latter npcx7 variants and npcx9 chips, only the new SHI
module is supported. Because NPCX7mnFA chip variants are not included in
the zephyr repo. We can remove the version control setttng.
