brcm47xx: Fix boot problem with wgt634u. 

Readd the workarround from the old version again which was removed in r22296 and refresh the patches.

This should close #7874

Thank you Russell Senior for testing.

The Netgear wgt634u uses a different format for storing the
configuration. This patch is needed to read out the correct
configuration. The cfe_env.c file uses a different method way to read
out the configuration than the in kernel cfe config reader.
