imx8mp levy: add bootselect via GPIO
This patch adds support for the PCAL6416 I2C gpio expander on the D18 / LEVY module to enable bootselect functionality on the B79 and ModularVision carrier boards via SMARC GPIO7.
Note: This patch only adds support for accessing the GPIO expander. Implementation of the bootselect functionality will be done in a separate patch.
