Fix repeated boot screen

[Ludy87]

The logo will appear twice, as you can see by enable BOOT_MARLIN_LOGO_ANIMATED

If the logo is too large to display more than one line of text, the first draw will display the first line of text and the second draw (q == 0) will draw the second line of text.

If I activate the BOOT_MARLIN_LOGO_SMALL it will still run twice, which is normal if the value is 2

The test to see whether is should run twice cannot be based simply on BOOT_MARLIN_LOGO_SMALL but should be based on how many "splash lines" are defined and whether there is enough space for two lines below the logo.

Now I understand what you mean, then I have to look at the size ratio.

Would that be an alternative?

I've merged a patch that should cover all cases.
