Subject: [PATCH 11/44] serial: xilinx_uartps: Switch to use hrtimer_setup()

There is a newly introduced hrtimer_setup() which will replace
hrtimer_init(). This new function is similar to the old one, except that it
also sanity-checks and initializes the timer's callback function.

Switch to use this new function.

Patch was created by using Coccinelle.
