Subject: serial: sh-sci: Stop using printk format %pCr

From: Geert Uytterhoeven <[e-mail]>

commit d63c16f8e1ab761775275adcf54f4bef7c330295 upstream.

Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
called in atomic context.

Replace it by open-coding the operation.  This is safe here, as the code
runs in task context.
