media: platform: mtk-mdp3: fix potential frame size overflow in mdp_try_fmt_mplane()

Fix overflow risk when setting certain formats whose frame size exceeds
a RGB24 with 7723x7723 resolution.

For example, a 7723x7724 RGB24 frame:
    1. bpl (byte per line) = 7723 * 3.
    2. Overflow occurs when bpl * 7724 * depth.
