From: Ashish Kumar <ashish.kumar@nxp.com>

mt25qu512a is rebranded after its spinoff from STM, so it is
different only in term of extended jedec ID, initial JEDEC id
is same as that of n25q512a.In order to avoid any confussion 
with respect to name new entry is added.
This flash is tested for Single I/O mode on LS1046FRWY although
it does support QUAD I/O.

mt35xu02g is Octal flash supporting Single I/O and QCTAL I/O
and has been tested on LS1028ARDB
