MLK-16755 video: fbdev: mipi_dsi_northwest: fix a linker error when do 64bit div

Compiling the 64-bit integer direct division statement by
32-bit GCC compiler may trigger below linker error:

"
drivers/built-in.o: In function `mipi_dsi_enable':
core.c:(.text+0x2ad48): undefined reference to `__aeabi_uldivmod'
core.c:(.text+0x2ad60): undefined reference to `__aeabi_uldivmod'
core.c:(.text+0x2ada4): undefined reference to `__aeabi_uldivmod'
core.c:(.text+0x2ade8): undefined reference to `__aeabi_uldivmod'
core.c:(.text+0x2aed4): undefined reference to `__aeabi_uldivmod'
drivers/built-in.o:core.c:(.text+0x2af00): more undefined references to
`__aeabi_uldivmod' follow
make: *** [vmlinux] Error 1
"

In this case, use 'do_div()' can solve this linker error.
This patch changes all the 'DIV_ROUND_CLOSEST()' to its
64-bit version 'DIV_ROUND_CLOSEST_ULL()' and also uses
'do_div()' to replace all the direct division operations
if required.
