   ## Summary
   
   1. risc-v/cmake: set llvm cputype only for LLVM based toolchain
   
   ```
   remove LLVM_CPUTYPE from compile line
   
   set llvm cputype only for LLVM based toolchain to avoid build break:
   
   riscv64-unknown-elf-gcc: error: unrecognized command-line option '-mcpu=sifive-u54'
   ```
   
   2. risc-v/cmake: configurable vendor ISA extensions
   
   ```
   merge below commit into cmake:
   
   1. risc-v/toolchain: configurable vendor ISA extensions
   
   This option allows the platform to enable some vendor-customized ISA extensions,
   E.g OpenHW, SiFive, T-Head.
   
   SiFive Intelligence Extensions:
       SiFive Vector Coprocessor Interface(VCIX): xsfvcp
       SiFive FP32-to-int8 Ranged Clip Instructions: Xsfvfnrclipxfqf
       SiFive Matrix Multiply Accumulate Instructions: Xsfvfwmaccqqq
       SiFive Int8 Matrix Multiplication Instructions: XSFvqmaccqoq
   Command Line:
       xsfvcp0p1_xsfvfnrclipxfqf0p1_xsfvfwmaccqqq0p1_xsfvqmaccqoq0p1
   
   2. "V" Standard Extension for Vector Operations
   3. "Q" Standard Extension for Quad-Precision Floating-Point
   ```
