[PATCH][V2] pinctrl: ti-iodelay: remove redundant pin < 0 check on unsigned int

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

pin is an unsigned int and therefore can never be < 0 so
this check is redundant. Remove the check and the associated
dev_err error message.

Fixes CoverityScan CID#1396438 ("Unsigned compared against 0")
