I think your build configuration would include both the meta-raspberrypi 
and meta-phosphor layers.
The meta-phosphor layer brings in the BMCWeb recipe [1] and BMCWeb 
enables Redfish by default [2].
So I think your approach should work, but I do not have experience 
setting up machines.
Andrew added a tutorial for this [3].

[1]: 
https://github.com/openbmc/openbmc/blob/master/meta-phosphor/recipes-phosphor/interfaces/bmcweb_git.bb
[2]: https://github.com/openbmc/bmcweb/blob/master/CMakeLists.txt#L37
[3]: https://gist.github.com/geissonator/77d4f6c6ed17bb0693b4251137f77fb4

The root password is configured in the phosphor-defaults.inc [4] (and 
other places such as in various EVB layers) and the root user is 
authorized to use redfish APIs per the bmcweb recipe ([1] again).

[4]: 
https://github.com/openbmc/openbmc/blob/master/meta-phosphor/conf/distro/include/phosphor-defaults.inc#L229

Note the default port for BMCWeb is 443 (HTTPS).

A few more questions:
1. How are you getting the RPI's IP address?  Are you just looking for 
it, or do you learn it by using the RPI's serial connection and signing in?
2. Are you using the RPI's serial port to debug?  If so, can you sign on 
as root?  If you can, does the systemctl command show the bmcweb service 
is running?  If it is, does bmcweb show any error messages for failed 
attempts to use Redfish APIs?

The default port is 443 (HTTPS) unless you changed it in a recipe. (This 
is not common.)
If you continue to enter "https:" you should not need to specify port.
