Switch all platforms to the MctpSerial uart-service

Every platform drove its uart-service through
`DefaultService::default_smbusespi` (SMBus/eSPI framing). Switch all
five to `MctpSerialService::default_mctp_serial` so the EC link speaks
DSP0253 serial (`MctpSerialMedium`) — the same framing the rest of the
stack now uses — and retire the SMBus/eSPI path.

`ec-test-cli` was updated to speak DSP0253 in odp-platform-common; bump
`EC_TEST_CLI_REV` to that revision so the dev-qemu integration test
exercises the unified wire format end to end.
