[fireball] 35285: Giannis Adamopoulos <[e-mail]> - Removes duplicated implementation of FrLdrLoadKernel, LoadDriver and LoadNlsFile from setupldr.c, use FrLdrLoadImage, FrLdrLoadNlsFile and FrLdrLoadDriver from reactos.c. - Also remove the call to RegInitializeRegistry as setupldr doesn't need the registry. - Make setupldr load the fastfat and ext2 drivers via txtsetup.sif, instead of hardcoding them in setupldr.c

Giannis Adamopoulos <johnyadams(a)hotmail.com>
- Removes duplicated implementation of FrLdrLoadKernel, LoadDriver and LoadNlsFile from
setupldr.c, use FrLdrLoadImage, FrLdrLoadNlsFile and FrLdrLoadDriver from reactos.c.
- Also remove the call to RegInitializeRegistry as setupldr doesn't need the
registry.
- Make setupldr load the fastfat and ext2 drivers via txtsetup.sif, instead of hardcoding
them in setupldr.c
