Constify a number of pinctrl_ops and pinmux_ops that are never modified
to allow the compiler to put them in read-only memory.

These are only assigned, either directly or via the bcm63xx_pinctrl_soc
struct, to the pctlops field in the pinctrl_desc struct and never
modified, so make them const to allow the compiler to put them in
read-only memory.

* [PATCH 2/2] pinctrl: bcm: Constify static pinmux_ops

These are only assigned, either directly or via the bcm63xx_pinctrl_soc
struct, to the pmxops field in the pinctrl_desc struct and never
modified, so make them const to allow the compiler to put them in
read-only memory.
