This patch changes the vboot EC sync code to use the new CBFS API. As a
consequence, we have to map the whole EC image file at once (because the
new API doesn't support partial mapping). This should be fine on the
only platform that uses this code (Google_Volteer/_Dedede family)
because they are x86 devices that support direct mapping from flash, but
the code was originally written to more carefully map the file in
smaller steps to be theoretically able to support Arm devices.
EC sync in romstage for devices without memory-mapped flash would be
hard to combine with CBFS verification because there's not enough SRAM
to ever hold the whole file in memory at once, but we can't validate the
file hash until we have loaded the whole file and for performance (or
TOCTOU-safety, if applicable) reasons we wouldn't want to load anything
more than once. The "good" solution for this would be to introduce a
CBFS streaming API can slowly feed chunks of the file into a callback
but in the end still return a "hash valid/invalid" result to the caller.
If use cases like this become pressing in the future, we may have to
implement such an API.
However, for now this code is the only part of coreboot with constraints
like that, it was only ever used on platforms that do support
memory-mapped flash, and due to the new EC-EFS2 model used on more
recent Chrome OS devices we don't currently anticipate this to ever be
needed again. Therefore this patch goes the easier way of just papering
over the problem and punting the work of implementing a more generic
solution until we actually have a real need for it.

Gerrit is able to add reviewers based on entries in the `MAINTAINERS`
file. For inclusion and exclusion matches either paths or regular
expressions can be used. The syntax is described in the header of the
file.
When matching a path, there are two sensible possibilities:
- `path/to/file` matches a file.
- `path/to/dir/` matches a folder including its contents recursively.
- `path/to/dir/*` matches all files in that folder, without recursing
into its subfolders.
The trailing slash in the second example is essential. Without it, only
the directory entry itself matches when, for example, the folder gets
deleted, renamed or its permissions get modified. Reviewers in the list
won't get added to changes of any files or directories below that path.
Thus, add a linter script to ensure a path match on a directory always
ends with `/` or `/*` as shown above.

Instead of counting consecutive matches (in `j`), check for a second
match directly in the control flow. Also, add some dedicated variables:
* `tap`: Keeps track of the tap value that resulted in a match and
is eventually programmed into the hardware.
* `tap2`: Is just temporarily used to search for another edge.
Keeping `tap` sync'ed with the hardware has the benefit that we don't
need to read the programmed value back for later fixups.
