[U-Boot] mt7623 bootup example

[Frank Wunderlich]

Just to be clear...i tested v2 patches on rc1 (https://github.com/frank-w/u-boot/tree/bpi-r2_v2) they working well.

v3 have additional depencies (swig,python-dev same on rc1&rc3) and bootargs seems not to be passed to kernel (rc1=bpi-r2_v3_old and rc3 = bpi-r2_v3)
