[PATCH 4/4] phy: cadence-torrent: Constify a u32[]

[Christophe JAILLET]

'cdns_torrent_refclk_driver_mux_table' is not modified in this driver.
And it is only used as a "const u32 *".

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  93578	   4798	     16	  98392	  18058	drivers/phy/cadence/phy-cadence-torrent.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  93606	   4790	     16	  98412	  1806c	drivers/phy/cadence/phy-cadence-torrent.o
