media: i2c: imx219: Fix test pattern window for 640x480 mode

The 640x480 mode specifies incorrect values for the TP_WINDOW_WIDTH and
TP_WINDOW_HEIGHT registers, which likely got copied from the 1640x1232
mode. They should be identical to the X_OUTPUT_SIZE and Y_OUTPUT_SIZE
registers as for all the other modes, to avoid cropping the test
pattern. Fix them.
