sfc: SFN4111T: Fix GPIO sharing between I2C and FLASH_CFG_1

Change sfn4111t_reset() to change only GPIO output enables so that it
doesn't break subsequent I2C operations.

Update comments to explain exactly what we're doing.

Add a short sleep to make sure the FLASH_CFG_1 value is latched before
any subsequent I2C operations.
