Xtensa improvements for v4.19:

- switch xtensa arch to the generic noncoherent direct mapping operations;
- add support for DMA_ATTR_NO_KERNEL_MAPPING attribute;
- clean up users of platform/hardware.h in generic Xtensa code;
- fix assembly cache maintenance code for long cache lines;
- rework noMMU cache attributes initialization;
- add big-endian HiFi2 test_kc705_be CPU variant.
