phy: cadence: Sierra: Constify a u32[]

'cdns_sierra_pll_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
60937 3894 16 64847 fd4f drivers/phy/cadence/phy-cadence-sierra.o

After:
=====
text data bss dec hex filename
60897 3878 16 64791 fd17 drivers/phy/cadence/phy-cadence-sierra.o
