fbdev: fix modedb docs in fb_find_mode 

Fix up the indenting that confused sphinx. To make sure we
don't have to make the examples unreadable with escaping just
put them in as block quotes, that seems the simplest solution.

*
* <xres>x<yres>[M][R][-<bpp>][@<refresh>][i][p][m]

*
* If 'M' is present after yres (and before refresh/bpp if present),
* the function will compute the timings using VESA(tm) Coordinated
* Video Timings (CVT). If 'R' is present after 'M', will compute with
* reduced blanking (for flatpanels). If 'i' or 'p' are present, compute
* interlaced or progressive mode. If 'm' is present, add margins equal
* to 1.8% of xres rounded down to 8 pixels, and 1.8% of yres. The chars
* 'i', 'p' and 'm' must be after 'M' and 'R'. Example:
