Haotian Zhang 6b860ae7cd pinctrl: stm32: fix hwspinlock resource leak in probe function 
[ Upstream commit 002679f79e ]

In stm32_pctl_probe(), hwspin_lock_request_specific() is called to
request a hwspinlock, but the acquired lock is not freed on multiple
error paths after this call. This causes resource leakage when the
function fails to initialize properly.

Use devm_hwspin_lock_request_specific() instead of
hwspin_lock_request_specific() to automatically manage the hwspinlock
resource lifecycle.
