[meta-freescale] LS1012A USB 2.0

[Tim Hammer]

Zhenhua -

Thank you. My understanding is that USB2 on the LS1012A was verified on the
QDS board; possibly with the QorIQ 1703 SDK?

There are *ls1012aqds* files in LSDK 18.03 (and thus in YP2.5), but perhaps
not all of the changes from the QDS work were brought forward?
