pwm: imx1: Don't disable clocks at device remove time

stable inclusion
from stable-5.10.52
commit 527bb29eb183cf1339164d2cc5c7b8aca625bb82
bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=527bb29eb183cf1339164d2cc5c7b8aca625bb82

--------------------------------

[ Upstream commit 1bc6ea31 ]

The .remove() callback disables clocks that were not enabled in
.probe(). So just probing and then unbinding the driver results in a clk
enable imbalance.

So just drop the call to disable the clocks. (Which BTW was also in the
wrong order because the call makes the PWM unfunctional and so should
have come only after pwmchip_remove()).

Fixes: 9f4c8f96 ("pwm: imx: Add ipg clock operation")
