Tyan S8226: Fix integer truncated warning
Fix Warning: sb700_cfg.c:129, GNU Compiler 4 (gcc), Priority: Normal large integer implicitly truncated to unsigned type [-Woverflow]
The issue here was that an 8 bit value was being placed into a 2-bit bitfield. The 8 bit value 0x2A was being used incorrectly - I believe the original intent of this value was to enable the SDIN pins 0, 1, & 2. Because it was getting truncated as it was put into AzaliaSdin0, this wasn't happening and only SDIN0 was being enabled.
UINT32 AzaliaSdin0 :2; //6 UINT32 AzaliaSdin1 :2; //8 UINT32 AzaliaSdin2 :2; //10 UINT32 AzaliaSdin3 :2; //12
* SDIN0 is define at BIT0 & BIT1 * 00 - GPIO PIN * 01 - Reserved * 10 - As a Azalia SDIN pin
I am leaving only SDIN0 enabled at this point to as not change the actual behavior on the platform.
