[NET] smc91x: add SMC91X_NOWAIT flag to platform data 

And also favors the usage of SMC91X_NOWAIT over the hardcoded SMC_NOWAIT
by converting "nowait" (module parameter overridable) to platform flag.

There are several possibilities:

  1. platform data present - preferred and use as is
  2. platform data absent  - use "nowait", it can be:
       a. SMC_NOWAIT if defined
       b. default to 0 if SMC_NOWAIT isn't defined
       c. overriden by module parameter
