pinctrl: Constify pointers to 'pinctrl_desc'

Pin controller core code only stores the pointer to
'struct pinctrl_desc' and does not modify it anywhere.  The pointer can
be changed to pointer to const which makes the code safer, explicit and
later allows constifying 'pinctrl_desc' allocations in individual
drivers.
