cover README.hardware: update installation instructions for beagleboard
Without having the hardware to test, these instructions should resolve the boot issues Yi experienced on the Beagleboard C4. These were arrived at through discussions on the freenode #beagle channel. Thanks to Ceriand and woglinde.
A physical test by any one of those Cc'd following the updated instructions would be appreciated.
The following changes since commit 72f06800bcf6f3d188b99bd0c359f5ef74879621:
u-boot: remove old SRCREV from poky-default-revisions.inc (2011-05-20 09:22:18 -0700)
