minilaketb : config phy(RTL8211E-VB) LED (torvalds#544)

Summary:
Summary :
1. config phy led, 1000M is amber LED, 100M/10M is green LED.
2. remove the CONFIG_FTGMAC100_NCSI for minilaketb, because minilaketb is dedicated lan.

Test Plan :
test on minilaketb pass
Closes facebookexternal/openbmc.quanta#544
