EBC0_B0CR should be set as 16-bit; through an ifdef merging typo it is
currently set incorrectly as 8-bit. This prevents 405LP wakeup from
succeeding and needs to be fixed.
Please apply to _2_4_devel and 2.5.

I've applied this to _2_4_devel, but not to 2.5 (I'm not really
up-to-date on 2.5 at the moment).
