mmc: sdhci-of-aspeed: Remove children before releasing SDC resources

Browse source

Probe failure and removal leave SDHCI child devices registered after the
parent clock and managed resources are released.

Unregister the OF children in reverse order before disabling the parent
clock on both paths. Use of_platform_device_destroy() because manual
child creation does not set the flag required by of_platform_depopulate().

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
