Macro regmap_update_bits can return a -ve on an error value so ret
needs to be an integer rather than a bool type.
Fixes warning found by static analysis with cppcheck:
[drivers/pinctrl/aspeed/pinctrl-aspeed.c:192]: (warning) Comparison of
a boolean expression with an integer other than 0 or 1.

Thanks Colin. Arnd independently discovered this bug and Joel and I
have CC'ed you on our responses there - the intent is to take Arnd's
patch.
