[PATCH v1 2/8] PCI: microchip: Remove cast warning for devm_add_action_or_reset() arg

[daire.mcnamara at microchip.com]

From: Daire McNamara <daire.mcnamara at microchip.com>

The kernel test robot reported that the ugly cast from
void(*)(struct clk *) to void (*)(void *) converts to incompatible
function type.  This commit adopts the common convention of creating a
trivial stub function that takes a void * and passes it to the
underlying function that expects the more specific type.

Fixes: 6f15a9c9f941 ("PCI: microchip: Add Microchip PolarFire PCIe controller driver")
