[ARM] 3750/3: Fix double VFP emulation for EABI kernels

Browse Source 
Patch from Daniel Jacobowitz

vfp_put_double didn't work in a CONFIG_AEABI kernel.  By swapping
the arguments, we arrange for them to be in the same place regardless
of ABI.  I made the same change to vfp_put_float for consistency.
