Correct gpepIncomingMessageHandler data signature

[konistehrad]

This assumes that it's the same across all versions. Of course, that's very difficult to validate given the state of EZSP documentation. However, on v8 this is absolutely correct, and I don't see a reason why it might be only v8 as opposed to everywhere else. Will close #593.

Note that the structure was lifted wholesale from zigbee-herdsman though I was able to verify their implement was correct at the data level and also polish it up a bit for us.

Thanks! Here's what is in the SDK source:

void ezspGpepIncomingMessageHandler(
  // The status of the GPDF receive.
  EmberStatus status,
  // The gpdLink value of the received GPDF.

  // The GPDF sequence number.
  uint8_t sequenceNumber,
  // The address of the source GPD.
  EmberGpAddress *addr,
  // The security level of the received GPDF.
  EmberGpSecurityLevel gpdfSecurityLevel,
  // The securityKeyType used to decrypt/authenticate the incoming GPDF.

  bool autoCommissioning,
  // Bidirectional information represented in bitfields, where bit0 holds

  // for outgoing gpdf.
  uint8_t bidirectionalInfo,
  // The security frame counter of the incoming GDPF.
  uint32_t gpdSecurityFrameCounter,

  uint8_t *gpdCommandPayload)

Actually I’m really sorry I pressed my EFR32 into running my home net while I wait for a replacement to ship. (EZSP does bespoke GPF processing that’s out of scope for my work right now.) I’ll dig back into this ASAP but it’ll be a bit.
