soc/amd/common/lpc/espi_util: use enum cb_err type for return values

Use enum cb_err as return type of all functions that aren't exposed
outside of this compilation unit. The checks if a function has returned
a failure are replaced with checks if the return value isn't CB_SUCCESS
which is equivalent if only those two values are used, but also detects
a failure if any unexpected value would be returned.
