[meta-qt5] Dropping tarball recipes from meta-qt5

[Martin Jansa <martin.jansa@gmail.com>]

Hi,

I'm still working on finishing 5.5-beta1 recipes for qt5, I'm getting
tired of maintaining 2 sets of patches and 2 versions of recipes in the
same layer branch.

1) Would people mind dropping 5.4 support in master branch (who wants to
use 5.4 can continue to use "fido" branch of meta-qt5, there are patches
for 5.4.2 git recipes as well).

2) Would people mind having only git recipes? It will be easier to
update them. Only disadvantages I can think of are the need to clone
from git and not being aligned with exact release for long time (git
recipes usually track newer revisions in e.g. 5.4 branch than 5.4.0 or
5.4.1 tarbal recipes.

If we all use the same version from the same recipes then we can test it
better and it will be much easier to maintain.
