Updates for riscv support

* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
  longer signed/unsigned int).

Changes come from internal branch commit a6723fc
