Subject: [PATCH] media: ov5695: enable vsync pin output

From: wuxy <wuxy@...land.corp-partner.google.com>

For Kukui project, the ov5695 vsync signal needs to
be set to output,from ov5695 datasheet,the related
register control methods as follows:

0x3002 Bit[7] FISIN/VSYNC output enable
0x3010 Bit[7] enable FISIN/VSYNC as GPIO controlled by register
0x3008 Bit[7] register control FISIN/VSYNC output

TEST= boot to shell
