toolchain: remove the old BR2_VFP_FLOAT option

Browse Source 
Now that we have a much better way of selecting between the various
VFP versions and capabilities, the BR2_VFP_FLOAT version no longer
makes sense. This commit gets rid of it, and adds the appropriate
Config.in.legacy code.

Due to a major refactoring of the floating-point handling of
the ARM architecture support, the BR2_VFP_FLOAT option has
been replaced with a choice of options that allows to select
between various VFP versions/capabilities.

Setting this option will enable the "-mfpu=vfp" option.
If your ARM CPU has a Vector Floating Point Unit (VFP)
and the toolchain supports the option, then the
code can be optimized.
Most people will answer N.
