[ Upstream commit c9ec155b5962233aff3df65210bd6a4788dee21c ]
The msm_serial driver has a predefined set of uart ports defined, which is allocated either by reading aliases or if no match is found a simple counter, starting at index 0. But there's no logic in place to prevent these two allocation mechanism from colliding. 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.
