Subject: [PATCH v2 1/1] arm64: dts: lx2160a: Fix the compatible string of LX2160A UART

Mark Kettenis told us that:
According to the NXP documentation, the LX2160A has a real PL011 UART.

Therefore, rewrite it to the compatible string of pl011. The property
"current-speed" specific to "arm,sbsa-uart" is also deleted.
