Subject: net: stnic: Fix up fallout from SH header migration.

asm/se.h moved to mach-se/mach/se.h, update the path. We could use
mach/se.h here also, but it's preferable to be explicit when there's
only a single supported mach-type.

Subject: maple: allow removal and reinsertion of keyboard driver module

Allow the removal (and subsequent reinsertion) of the maple_keyb (maple
keyboard) driver by adding a working removal function.

Also tidy long lines.
