Add Faraday's ftgmac100 (gigabit ethernet) MAC controller's driver.

Signed-off-by: Macpaul Lin macpaul@andestech.com --- Changes for v2: - Coding Style cleanup - Makefile Order sorted - Volatile statement eliminated - Error handling added - Autonegotiation timeout value rechecked - Link speed detection code is reduced - Logic of autonegotiation and Link speed update reorganized - Redundent registers offset table cleared - The explaination of sub configuration of this driver has moved into README

Changes for v3: - Coding Style clean up about - 2 continue blank line - incorrect multi-line comment style - useless else statement and return value statement - make multi-line statement into single line which doesn't exceed 80 chars - brance with multi-line statement (comments included before one line code)
