[PATCH, RFC 08/22] OMAPDSS: DPI needs DSI

[Arnd Bergmann]

The dpi.c file cannot be build correctly when the dsi.c file is
disabled in Kconfig. This clarifies the dependency in Kconfig
to avoid build errors:

drivers/video/omap2/dss/dpi.c: In function 'dpi_calc_pll_cb':
drivers/video/omap2/dss/dpi.c:181:2: error: implicit declaration of function 'dsi_hsdiv_calc' [-Werror=implicit-function-declaration]
drivers/video/omap2/dss/dpi.c: In function 'dpi_dsi_clk_calc':
drivers/video/omap2/dss/dpi.c:201:2: error: implicit declaration of function 'dsi_get_pll_clkin' [-Werror=implicit-function-declaration]
