media: amlogic: c3-mipi-csi2: Handle 64-bits division
The kernel test robot reports the following error when building on
Hexagon with hexagon-allmodconfig.
ERROR: modpost: "__hexagon_divdi3"
[drivers/media/platform/amlogic/c3/mipi-csi2/c3-mipi-csi2.ko] undefined!
The error is caused by using DIV_ROUND_UP() with a 64 bits divisor with
a 32-bit dividend, which on Hexagon and clang-17 is resolved with a call
to the __hexagon_divdi3() helper function, part of the compiler support
library and not available when building Linux.
Use DIV_ROUND_UP_ULL() to fix the build error and avoid calling the
__hexagon_divdi3() helper function.
