rockchip: resource: support parse "logo" partition picture 

We provide a "logo" partition for user to store logo.bmp
and update from kernel user space dynamically.

This patch follows the rkdevelop usage:
- Only support store one picture named "logo.bmp";
- Use "dd" command to generate partition image with logo.img
  eg: "dd if=logo.bmp of=logo.img count=1 bs=19456"
