[PATCH v2 2/7] MdeModulePkg/EhciDxe: Use BaseLib linked list iteration macros

["Michael Kubacki" <michael.kubacki@outlook.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1959

Replaces usage of the linked list iteration macros defined in Ehci.h
with the common definition in BaseLib.h.
