Subject: [RFC PATCH 1/2] arm64: amlogic: add new ARCH_AMLIPC for IPC SoC

From: Xianwei Zhao <xianwei.zhao@...ogic.com>

The C series SoCs are designed for smart IP camera
applications, which does not belong to Meson series.
So, Add ARCH_AMLIPC for the new series.

There are now multiple amlogic SoC seies supported, so group them under
their own menu. we can easily add new platforms there in the future.
Introduce ARCH_AMLOGIC to cover all Amlogic SoC series.

No functional changes introduced.
