- TCA9534: Added I2C GPIO expander driver (`src/dev/tca9534.h`) with shared-bus and owned-bus init, plus `TCA9534_GPIO` example.

### Bug Fixes

- CMake: `DATA_IN_D2_SRAM` is now defined, so `SystemInit()` enables the D2 AHB SRAM blocks that hold the DMA buffers. The Makefile build already did this.

## v8.1.0
