[PATCH 2/4] phy: cadence-torrent: Constify struct cdns_torrent_vals_entry

[Christophe JAILLET]

'struct cdns_torrent_vals_entry' is not modified in this driver.

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
  85130	  13214	     16	  98360	  18038	drivers/phy/cadence/phy-cadence-torrent.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  92234	   6078	     16	  98328	  18018	drivers/phy/cadence/phy-cadence-torrent.o

Compile tested-only.
