Revert "Fonts: Make font size unsigned in font_desc"

This reverts commit 78e008dca2 which is
commit 7cb415003468d41aecd6877ae088c38f6c0fc174 upstream.

It breaks the Android kernel ABI and is not needed for Android devices,
so it is safe to revert for now.  If it is determined that it is needed
in the future, it can be brought back in an abi-preserving way.
