phy: cadence: Sierra: Constify struct cdns_sierra_vals

'struct cdns_sierra_vals' 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
60521 4310 16 64847 fd4f drivers/phy/cadence/phy-cadence-sierra.o

After:
