[PATCH v3 1/4] MdeModulePkg/SdMmcPciHcDxe: Add an optional parameter in NotifyPhase

[Marcin Wojtas <mw@semihalf.com>]

In order to ensure bigger flexibility in the NotifyPhase
routine of the SdMmcOverride protocol, enable using an
optional phase-specific data. This will allow to exchange
more information between the protocol producer driver
and SdMmcPciHcDxe in the newly added callbacks.
