net: Handle disabling of compilation for SPL builds

Whilst the net/ directory is excluded from libs-y when
CONFIG_SPL_NET_SUPPORT is disabled, this does not prevent SPL builds
trying to compile net/ objects. During SPL builds overwrite the value of
CONFIG_NET with CONFIG_SPL_NET_SUPPORT to exclude compilation during SPL
builds.

This needs to be fixed the same way we have in other cases and that is
for CONFIG_SPL_NET_SUPPORT to become CONFIG_SPL_NET and then Makefiles
use 'obj-$(CONFIG_$(SPL_)NET) += ...' and so forth.  Thanks!
