pinctrl: qcom: constify tiles properly

compiler warns:
drivers/pinctrl/qcom/pinctrl-qcs404.c:1660:11:
	warning: initialization discards 'const' qualifier
	from pointer target type [-Wdiscarded-qualifiers]

The tiles are array of strings rightly defined as
"const char * const qcs404_tiles" so the member holding should also be
defined similarly. So update tiles to "const char * const *"

Fixes: 1c1880fb7706 ("pinctrl: qcom: Support dispersed tiles")

Thanks Vinod.

Linus picked the same fix from Arnd last week, so we're good.
