add support for pca9538, pcal9539. Add support for pcal6408 and pcal6416, which is originally supported by pcal64xxa driver. These device has the same register layout as pcal9538 and pcal9539 respectively, which means they can be seamlessly supported by pca_series driver. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>

The reset function is originally designed to have no return value. If the GPIO toggle fails, there's no indication for failure until I2C transaction fails. Account for this by adding return value to the reset function. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>
Enables pca_series driver to set drive strength for part no with PCA_HAS_LATCH capability. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>
On certain platforms I2C is not enabled by default, causing build error. Change pca_series driver to select I2C. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>
pca6416a driver can be replaced by pca_series driver, which covers a larger number of devices. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>

Preserving pca_series commits for CI check. Once CI passes I will drop commits from the other PR and make it clean for review. |

Enable pcal6408 gpio expander on FRDM-IMX93 board. This expander has its reset pin controlled by another expander, and both expanders is driven by the same pca_series driver. To guarentee correct init order, pcal6408 is set to deferred init in a board init function. Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>
