Incorrect stdout-path for UART in Device Tree

[zlaazlaa]

In the demo, Linux is bound to a PL011 UART at 0x1c090000, but the DTS defines the UART at 0x1c0a0000. Despite this, the boot log still appears on the terminal (because the correct set of console in bootargs). The issue arises because the stdout-path in the DTS incorrectly points to /pl011@1c090000, which does not exist. It should instead point to /pl011@1c0a0000. Fixing this mismatch will correctly configure the console output from the start.
