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: ===== text data bss dec hex filename 60937 3894 16 64847 fd4f drivers/phy/cadence/phy-cadence-sierra.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/0ccfd259fdf40475c89cfb22a64c6388e7c646b4.1720723132.git.christophe.jaillet@wanadoo.fr Signed-off-by: Vinod Koul <vkoul@kernel.org>
