PCI: meson: Remove cast between incompatible function type
Rather than casting void(*)(struct clk *) to void (*)(void *), that
forces conversion to an incompatible function type, replace the cast
with a small local stub function with a signature that matches what
the devm_add_action_or_reset() function expects.
The sub function takes a void *, then passes it directly to
clk_disable_unprepare(), which handles the more specific type.
Reported by clang when building with warnings enabled:
drivers/pci/controller/dwc/pci-meson.c:191:6: warning: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict]
(void (*) (void *))clk_disable_unprepare,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
No functional changes are intended.
