[RFC PATCH 6/7] mtd: replace direct wbinvd invoke with kernel api

[Reinette Chatre]

The nettel driver contains a few direct wbinvd invocations in the form:
__asm__ ("wbinvd")

Replace all of these calls with the kernel API "native_wbinvd()" that
translates to same as "asm volatile("wbinvd" : : : "memory")" and
provides a central location where calls to this destructive instruction
can be tracked and potentially acted on.
