Since commit a5a4c1d5a3 ("dts: update to v5.13-rc1"), which synced
kernel dts, USB-OTG port on phyFLEX board was set to work only in
peripheral mode. This has to do with phyFLEX baseboard hardware bug,
which prevents correct USB OTG ID pin detection in kernel code.
Unlike linux kernel, barebox doesn't support OTG auto-detection mode via
ID pin. In barebox, user has to select desired USB mode of operation by
setting 'otg.mode' variable. Thus set the 'dr_mode' property to "otg" to
be able to later select USB OTG operating mode at runtime (either host
or peripheral).

- rather than deleting the dr_mode property, set the property to "otg"
to explicitly set the mode to OTG
