media: ov08x40: Extend sleep after reset to 5 ms

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.
