RISC-V: Minimal support for ZC* extensions.
This patch is the minimal support for ZC* extensions, include the extension
name, mask and target defination. Also define the dependencies with Zca
and Zce extension. Notes that all ZC* extensions depend on the Zca extension.
Zce includes all relevant ZC* extensions for microcontrollers using. Zce
will imply zcf when 'f' extension enabled in rv32.
