Chin Liang See 3ab019e1dc socfpga: Fix SOCFPGA build error for Altera dev kit
To fix the build error when build for Altera dev kit, not
virtual target. At same time, set the build for Altera dev
kit as default instead virtual target. With that, U-Boot
is booting well and SPL still lack of few drivers.
