Blackfin: remove "config IP_CHECKSUM_L1"
Blackfin: remove "config IP_CHECKSUM_L1"

The only user of Kconfig symbol IP_CHECKSUM_L1 got removed in v2.6.33,
with commit ddf9ddacef0989fdeb22e182212a232488f0f3ad ("Blackfin: convert
to generic checksum code"). We can remove the Kconfig entry for this
unused symbol now.
