feat: add PSRAM support and related tests

- Updated formal.mk to include PSRAM in formal verification targets and source files.
- Modified software.mk to include psram_math.c for HAL.
- Enhanced pin_map.json to map GPIO pins for PSRAM control signals.
- Refactored ip_ribp_wrapper.sv to integrate PSRAM interface and remove unused ribp interfaces.
- Updated rtl_style_audit.json to include PSRAM related files.
- Added PSRAM testbench (psram_tb.sv) for integration testing.
- Created test_psram.py to validate PSRAM controller functionality and register offsets.
- Adjusted memory map tests to reflect new PSRAM address space and size.
