mfd: cros_ec: add ec_align macros

To reduce code and improve performance of the embedded controller firmware, pragma __aligned(2) or __aligned(4) are used when alignment to 16 or 32 bit boundary is expected. Define all ec_align to packed when compiling kernel.

	200	+ * the parent structure. This is particularly important if the sub-structure
	201	+ * will be passed as a pointer to another function, since that function will
	202	+ * not know about the misaligment caused by the parent structure's packing.
	203	+ *
	204	+ * Also be very careful using __packed - particularly when nesting non-packed
	205	+ * structures inside packed ones. In fact, DO NOT use __packed directly;
	206	+ * always use one of these attributes.
