Read kernel body load address from preamble by default
The default behavior of dump_kernel_config is changed from using
CROS_32BIT_ENTRY_ADDR to reading from kernel preamble. The main
motivation for this change is in preparation for ARM boards of which
kernel body load address cannot be CROS_32BIT_ENTRY_ADDR. Since we do
not want that all ARM calling sides of dump_kernel_config have to carry
the kloadaddr argument, it would be better to let dump_kernel_config
read this address from the kernel preamble by default.
BUG=chromium-os:28077
TEST=Run dump_kernel_config w/ and w/o this change
