[PATCH] ppc64: Fix find_udbg_vterm()
The find_udbg_vterm() used to initialize the early boot console
on LPAR machines will not work properly on some recent pSeries
because the firmware is playing tricks with the "phandle" values
used to identify firmware nodes. This patch fixes that by using
the full path instead.
