[meta-xilinx] [meta-xilinx-bsp][PATCH] arm-trusted-firmware.inc: Add support for atf to use 2nd UART

[Manjukumar Matha]

From: Jaewon Lee <jaewon.lee at xilinx.com>

Add ZYNQMP_CONSOLE flag to EXTRA_OEMAKE to add support for the 2nd UART.
If ZYNQMP_CONSOLE is set to cadence or cadence0, it will use UART 0 and
if set to cadence1, it will use UART 1. The default value is set to
cadence.

Change do_configure to perform make clean. Without this change,you must
manually clean sstate before building with the new value of
ZYNQMP_CONSOLE, which is not the desired behavior.
