[PATCH] pinctrl: ret needs to be an int for -ve return value from regmap_update_bits

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

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.
