drivers/wifi/generic.c: Upper case the AML WiFi name as required by spec 

ACPI 6.3, ASL 20.2.2 (Name Objects Encoding) states:

  LeadNameChar := 'A'-'Z' | '_'
  NameChar := DigitChar | LeadNameChar

Hence, the Intel WiFi names generated in ASL are required to be
upper-cased letters.

BUG=b:141206986
TEST=Reflash and confirmed SSDT table has correct name.
