board: gw_ventana: gsc: fix GSC read/write functions
commit 7c84319af9c7 ("dm: gpio: Correct use of -ENODEV in drivers")
changed the return code for an I2C NAK from -ENODEV to -EREMOTEIO.
Update the gsc_i2c_read and gsc_i2c_write functions for this change
to properly retry the transaction on a NAK meaning the GSC is busy.
Fixes: 7c84319af9c7 ("dm: gpio: Correct use of -ENODEV in drivers")
