phy: cadence-torrent: Constify struct cdns_torrent_vals_entry
'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
