Subject: thermal: bcm2835: Stop using printk format %pCr

From: Geert Uytterhoeven <[e-mail]>

commit bd2a07f71a1e2e198f8a30cb551d9defe422d83d upstream.

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

Replace it by printing the variable that already holds the clock rate.
Note that calling clk_get_rate() is safe here, as the code runs in task
context.
