Some users are reporting that ov08x40_identify_module() fails to identify the chip reading 0x00 as value for OV08X40_REG_CHIP_ID. Intel's out of tree IPU6 drivers include some ov08x40 changes including adding support for the reset GPIO for older kernels and Intel's patch for this uses 5 ms. Extend the sleep to 5 ms following Intel's example, this fixes the ov08x40_identify_module() problem.
