The msm_serial driver uses a simple counter to determine which port to
use when no alias is defined, but there's no logic to prevent this from
not colliding with what's defined by the aliases. As a result either
none or all of the active msm_serial instances must be listed as
aliases.
Define blsp1_uart3 as "serial1" to mitigate this problem.
