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.

media: platform: Add C3 ISP driver
The C3 ISP supports multi-camera and multi-exposure HDR, integrates advanced imaging technologies for optimal quality, and drives the core pipeline to transform raw sensor data into high-fidelity images through demosaicing, color correction, and tone mapping operations.
