[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
