media: rkvdec: use DIV_ROUND_UP() for CTB counts
Use DIV_ROUND_UP() when computing HEVC coding tree block counts
instead of open-coding the same rounding expression. This keeps the
rounding intent explicit without changing behavior.
Found using a Coccinelle rule generated from the DIV_ROUND_UP() macro
definition.
