Subject: [PATCH] arm64: dts: qcom: msm8998-mtp: Add alias for blsp1_uart3

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.

Fixes: 4cffb9f2c700 ("arm64: dts: qcom: msm8998-mtp: Enable bluetooth")
