ISO15118-2 AC SupportedEnergyTransferMode setting issue

[nxpOTS]

Describe the bug

In ISO15118-2 ServiceDiscoveryRes message the SupportedEnergyTransferMode entry is sent as AC_three_phase_core even though the HardwareDriver module used sets max_phase_count_import, min_phase_count_import, max_phase_count_export, max_phase_count_export to 1.

Expectation would have been for it to be AC_single_phase_core, as all phase counts point to 1 (import and export).

To Reproduce

I've used 2025.07 release, with implementation of Hardware driver for custom board similar to YetiDriver.
Set max_phase_count_import, min_phase_count_import, max_phase_count_export, max_phase_count_export to 1 in the used Hardware Driver and configure an ISO15118-2 AC charging session. Check the ServiceDiscoveryRes message contents, as the SupportedEnergyTransferMode entry is sent as AC_three_phase_core even though there is no three phase hardware support.

Anything else?
