The existing ChromiumOS bootmeth only supports reading a single kernel
partition, either 2 or 4. In fact there are normally two options
available.
Use the GUID to detect kernel partitions, with the BOOTMETHF_ANY_PART
flag, so that bootstd does not require a valid filesystem before calling
the bootmeth.

It is not a parse error to have a default value of "0" for a "hex" type

same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a

The current bootflow-iteration algorithm reads the bootflow file into
an allocated memory buffer so it can be examined. This works well in
most cases.
However, while the common case is that the first bootflow is immediately
booted, it is also possible just to scan for available bootflows, perhaps
selecting one to boot later.
Even with the common case, EFI bootflows can be quite large. It doesn't
make sense to read it into an allocated buffer when we have kernel_addr_t
providing a suitable address for it. Even if we do have plenty of malloc()
space available, it is a violation of U-Boot's lazy-init principle to
read the bootflow before it is needed.
So overall it seems better to make a change.
Adjust the logic to read just the size of the EFI file at first. Later,
when the bootflow is booted, read the rest of the file into the designated
kernel buffer.
