Subject: [PATCH v2] serial: xilinx_uartps: kill CONFIG_OF conditional

The Zynq platform requires the use of CONFIG_OF.  Remove the #ifdef
conditionals in the uartps driver.  Make dependency explicit in Kconfig.

Signed-off-by: Josh Cartwright <josh.cartwright@...com>

Michal-

Here's a version of this patch outside of my COMMON_CLK patchset as you
requested ontop of your arm-next branch.  An explicit dependency was
added in Kconfig as you had suggested.

Thanks,
   Josh
