Subject: [PATCH] smc91x: sh solution engine fixes.

The current smc91x I/O routines ifdef the solution engine subtypes
individually, which is rather bogus, as they can simply use
CONFIG_SOLUTION_ENGINE instead. This fixes it for some of the other
solution engines that weren't included in the ifdef list (SH7206
specifically).

There are also inb/outb definitions which are totally bogus (missing
brackets in _both_ cases, SMC_CAN_USE_8BIT == 0, and even better, they
try to use a 16-bit access to fake 8-bit access). Kill that nonsense off
completely.
