This check should now be done whatever mode buildman is running in, since

patman: Add a -m option to avoid copying the maintainers

The get_maintainers script is a useful default, but sometimes is copies
too many people, or takes a long time to run.

Add an option to disable it and update the README.

sf: Add an empty entry to the parameter list

The list is supposed to be terminated with a NULL name, but is not. If a
board probes a chip which does not appear in the table, U-Boot will crash
(at least on sandbox).

dm: core: Allow device_bind() to used without CONFIG_OF_CONTROL

The sequence number support in driver model requires device tree control.
It should be skipped if CONFIG_OF_CONTROL is not defined, and should not
require functions from fdtdec.

dm: avoid dev->req_seq overflow

Since dev->req_seq value is initialized from "reg" property of fdt node,
there is posibility, that address value contained in fdt is greater than
INT_MAX, and then value in dev->req_seq is negative which led to probe()
fail.

This patch fix this problem by ensuring that req_seq is positive, unless
it's one of errno codes.
