The current driver supports more than just SiFive PLICs at present and, where possible, future PLIC implementations will also use this driver. As every supported RISC-V SoC selects the driver directly in Kconfig.socs there's no point in exposing this kconfig option to users. The Kconfig help text, in its current form, is misleading. There's no point doing anything about that though, as it will no longer be user selectable. Remove it.
