gpio: mvebu: Make use of devm_pwmchip_add

Browse Source 
[ Upstream commit 1945063eb5 ]

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: 757642f9a5 ("gpio: mvebu: Add limited PWM support")
