MLK-12054-1 media: video: fix multiple definition error in MIPI DSI driver

When enable CONFIG_FB_MXC_MIPI_DSI, meet following compiling error.

drivers/video/fbdev/mxc/mipi_dsi_samsung.o: In function `mipi_dsi_pkt_write':
mipi_dsi_samsung.c:(.text+0x818): multiple definition of `mipi_dsi_pkt_write'

move three dsi packet related functions to mipi_dsi_info
structure. This will avoid the multiple definition compiling
issue. This is what the commit f54c7527895575a2e474b17a4752724977b898ea does
in 3.14.y
