feat(zynqmp): dedicate console for boot and runtime
Introduce a build-time parameter (CONSOLE_RUNTIME) to select
separate runtime console options. For boot-time console, remove
the runtime flag and add a boot/crash flag. Additionally,
introduce an RT_CONSOLE_IS macro to check different UART types.
Implement a common function, console_runtime_init(), to initialize
the runtime console. Ensure that all platforms have access to
this feature.
The current implementation utilizes a single console for boot,
crash, and runtime. Make sure that the dedicated console integrates
into runtime and crash scenarios.
