[PATCH v4 1/3] media: rockchip: rkisp1: fix comment about number of histogram sub-windows

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner at theobroma-systems.com>

The histogram data is divided into 16 sub-windows, not 25.
See RKISP1_CIF_ISP_HIST_BIN_N_MAX being defined as 16 for reference
and this also matches the datasheet.
