Remove some redundant assignments, that have no effect on
'make jazz_defconfig':

CONFIG_INET_XFRM_MODE_TRANSPORT=m
CONFIG_INET_XFRM_MODE_TUNNEL=m
CONFIG_CRYPTO_HMAC=y

Also drop the settings relating to crypto, wireless, advanced
networking etc. The Kconfig defaults for these options are fine.

This reduces the size of vmlinux so it can be launched by
"NetBSD/arc Bootstrap, Revision 1.1", which is conveniently available
on NetBSD/arc 5.1 ISO images.
