media: i2c: imx477: Correct minimum exposure lines

The minimum number of exposure lines value (IMX477_EXPOSURE_MIN) was
previously 20 but this is not correct. The datasheet is not completely
explicit, however the new value of 4 has been tested with all the
sensor modes supported by this driver, and matches the lowest exposure
value of 114us that could be achieved wtih Raspberry Pi's legacy
firmware driver.
