Strago: I2C port support added and SPI Flash Size corrected

Browse Source 
I2C ports initialized as per board design. Modules
assigned to its corresponding I2C port numbers
Altered the SPI flash size to match the Braswell Ref Design board

BUG=None
BRANCH=None
TEST=Tested all I2C modules on all ports using i2cscan and i2cxfer
console commands
