[PATCH 2/2] soc: microchip: mpfs-mss-top-sysreg: Fix resource leak on driver unbind

[Felix Gu]

Use devm_mfd_add_devices() instead of mfd_add_devices() to ensure
child devices are properly removed when the driver unbinds.

Fixes: 4aac11c9a6e7 ("soc: microchip: add mfd drivers for two syscon regions on PolarFire SoC")
