Subject: [PATCH 04/15] mx23: Fix pad voltage selection bit
On mx23 the pad voltage selection bit needs to be always '0', since '1' is a
reserved value.
For example:
Pin 108, EMI_A06 pin voltage selection:
0= 1.8V (mDDR) or 2.5V (DDR1);
1= reserved.
Fix the pad voltage definitions for the mx23 case.
