Name : STFLASH_Init()
Description : Generates a linked list element for each instance called,
into which the caller's InitParams are copied. Also
attempts to Read the Electronic Signature to identify
the device, which is returned in STFLASH_Params_t when
GetParams() is called.
Parameters : ST_DeviceName_t Name of the Flash bank, and a pointer to
STFLASH_InitParams_t InitParams data structure.
Return Value : ST_ErrorCode_t specified as
ST_NO_ERROR No errors occurred
ST_ERROR_NO_MEMORY Insufficient memory free
ST_ERROR_ALREADY_INITIALISED Bank already initialised
ST_ERROR_BAD_PARAMETER Error in parameters passed
