For samsung,s5pv210-mipi-video-phy compatible PHYs the second cell in the
PHY specifier identifies the PHY and its meaning is as follows::
0 - MIPI CSIS 0,
1 - MIPI DSIM 0,
2 - MIPI CSIS 1,
3 - MIPI DSIM 1.
samsung,exynos5420-mipi-video-phy and samsung,exynos5433-mipi-video-phy
support additional fifth PHY::
4 - MIPI CSIS 2.
