robotrovsky 21912b95f4 Bugfix I_DELAY macro
When compiling

> const ulp_insn_t program[] = {
> I_DELAY(1)
> };

with the xtensa-esp32-elf-g++ compiler i always got the error:

> sorry, unimplemented: non-trivial designated initializers not supported
>
>        };

This was due to the different order in the macro and the struct. The struct has another order of the fields (opcode, unused, cycles) vs (cycles, unused, opcode):
>    struct {
>        uint32_t cycles : 16;       /*!< Number of cycles to sleep */
>        uint32_t unused : 12;       /*!< Unused */
>        uint32_t opcode : 4;        /*!< Opcode (OPCODE_DELAY) */
>    } delay;                        /*!< Format of DELAY instruction */

After updating the order in the macro it is possible to compile with the g++ compiler.
