Xilinx: ARM: UART: clear pending irqs before enabling irqs
The Boot ROM has an issue which will cause the driver to
lock up as pending irqs are not being cleared. With them
cleared it prevents that issue.
This patch is needed for the current (3.9-rc3) mainline kernel. I guess
it went unnoticed, because it was only tested with u-boot up until now.
And u-boot maybe handles this.
