Subject: [PATCH v2] usb: typec: mux: select not-visible INTEL_SCU_IPC

Use "select INTEL_SCU_IPC" instead of depending on it since it is
not a visible Kconfig symbol and it may not otherwise be set/enabled.

Fixes: b62851491a55 ("usb: typec: mux: Convert the Intel PMC Mux driver to use new SCU IPC API")
