ARM semihosting implementations in "common-semi-target.h"
must de-reference the target CPUArchState, which is declared
in each target "cpu.h" header. Include it in order to avoid
when refactoring:

  In file included from ../../semihosting/arm-compat-semi.c:169:
  ../target/riscv/common-semi-target.h:16:5: error: use of undeclared identifier 'RISCVCPU'
     16 |     RISCVCPU *cpu = RISCV_CPU(cs);
        |     ^
