net: dm9000: Drop dm9000.h and staticize SROM access

Browse Source 
Dispose of dm9000.h because none of the function prototypes declared in
it are called anywhere in the codebase. Staticize dm9000_read_srom_word()
because it is now called only from within the dm9000 driver. Drop
dm9000_write_srom_word() because it is no longer used.
