Subject: [PATCH 5.15 086/135] gpio: mvebu: drop pwm base assignment

From: Baruch Siach <baruch@...s.co.il>

[ Upstream commit e5f6e5d554ac274f9c8ba60078103d0425b93c19 ]

pwmchip_add() unconditionally assigns the base ID dynamically. Commit
f9a8ee8c8bcd1 ("pwm: Always allocate PWM chip base ID dynamically")
dropped all base assignment from drivers under drivers/pwm/. It missed
this driver. Fix that.
