[ Upstream commit 1945063eb59e64d2919cb14d54d081476d9e53bb ]
This allows to get rid of a call to pwmchip_remove() in the error path. There
is no .remove function for this driver, so this change fixes a resource leak
when a gpio-mvebu device is unbound.
Fixes: 757642f9a584 ("gpio: mvebu: Add limited PWM support")
