Pull request overview

This PR updates the wolfHAL driver interfaces to accept generic data buffers (void* / const void*) instead of byte-specific (uint8_t*) pointers across SPI, Flash, RNG, Ethernet, and Block devices, aligning the public APIs and concrete driver implementations.

Changes:

• Updated driver vtables and public APIs to use void*/const void* for data buffers (SPI SendRecv, Flash Read/Write, RNG Generate, Eth Send/Recv, Block Read/Write).
• Updated platform drivers and bus-device drivers to cast void* buffers to byte pointers internally.
• Updated core dispatch tests to match the new driver function signatures.
