mtd: spi-nor-tiny: annotate switch/case fallthrough

Browse Source 
The SPI NOR code uses an implicit switch/case fallthrough when checking
different vendors to determine how to deal with extended addressig modes.

Add our "fallthrough;" statement-like macro before some label in the
4-byte addressing mode code, to avoid a warning when GCC's
-Wimplicit-fallthrough warning option is enabled.
