drivers/net: delete orphaned MCA ibmlana driver content

In commit 8900081108fc21ee51036585de432c6512ddf6b4 ("drivers/net: delete
all code/drivers depending on CONFIG_MCA") most of the MCA drivers went,
including the Kconfig/Makefile hooks for ibmlana, but it seems that I
missed the "git rm" on these actual driver files, and with the namespace
overlap with machine check architecture, it got missed by various git
grep type checking done at that time.
