target/arm/cpu-features: Include missing 'hw/registerfields.h' header

target/arm/cpu-features.h uses the FIELD_EX32() macro
defined in "hw/registerfields.h". Include it in order
to avoid when refactoring unrelated headers:

  target/arm/cpu-features.h:44:12: error: call to undeclared function 'FIELD_EX32';
  ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
      return FIELD_EX32(id->id_isar0, ID_ISAR0, DIVIDE) != 0;
             ^
