i2c: algo: pca: Fix chip reset function for PCA9665
The parameter passed to pca9665_reset is adap->data (which is bus driver specific), not i2c_algp_pca_data *adap. pca9665_reset expects it to be i2c_algp_pca_data *adap. All other wrappers from the algo call back to the bus driver, which knows to handle its custom data. Only pca9665_reset resides inside the algorithm code and does not know how to handle a custom data structure. This can result in a kernel crash. Fix by re-factoring pca_reset() from a macro to a function handling chip specific code, and only call adap->reset_chip() if the chip is not PCA9665.
