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.

$ more src/vendorcode/amd/cimx/sb700/SBTYPE.h
        […]
        UINT32  AzaliaSdin0     :2;                     //6
        UINT32  AzaliaSdin1     :2;                     //8
        UINT32  AzaliaSdin2     :2;                     //10
        UINT32  AzaliaSdin3     :2;                     //12
        $ more src/mainboard/tyan/s8226/sb700_cfg.h
        […]
         *  SDIN0 is define at BIT0 & BIT1
         *   00 - GPIO PIN
         *   01 - Reserved
         *   10 - As a Azalia SDIN pin
         *  SDIN1 is define at BIT2 & BIT3
         *  SDIN2 is define at BIT4 & BIT5
         *  SDIN3 is define at BIT6 & BIT7
         */
        #ifndef AZALIA_SDIN_PIN
        #define AZALIA_SDIN_PIN              0x2A
        #endif
        […]
        $ more src/mainboard/tyan/s8226/sb700_cfg.c
        […]
        	sb_config->AzaliaSdin0 = AZALIA_SDIN_PIN;
        […]

The 8 bit value 0x2A (binary 00 10 10 10), 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.

I am leaving only SDIN0 enabled at this point to as not change the
    actual behavior on the platform.
