[PATCH 4/6] Revert "cmd: boot: Add '-edl' option to reset command documentation"

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

This reverts commit ef06c5d76ff46d488df201cc679f148b0140fd7a.

The args support for the sysreset uclass contains a logic bug. The first
sysreset device implementing the request_arg callback will consume the
args, not support the specified arg and thus return -EPROTONOSUPPORT
which will stop the iteration over all sysreset devices.

This is an issue if one has multiple sysreset devices and each with
support for different (valid) args. If a sysreset device implements a
-dummy argument and another -foo and one calls reset -dummy on the
U-Boot CLI, it'll depend on which sysreset device will be attempted
first. If it is the one implementing -foo, it'll return it doesn't
support the argument with -EPROTONOSUPPORT in which case the device
implementing -dummy will never be attempted and instead we'll do a cold
reset which is very likely not what's expected.
