arm: rmobile: alt: Add ethernet function B support

Browse source 
Ethernet function of Alt board can select normal and B by DIP switch
on board. But user need to set not only DIP switch but also pin function.
This adds pin function of Ethernet function B. This can select from Kconfig.

ALT board can use default ethernet and etnernet B function.
This config set pin function of ethenet B. You also needt to change
DIP switch of board in order to use this function.
