On omap, the sdhci.omap driver may kill eMMC

[Jan Kardell]

It is reported that in some circumstances aggressive PM in shdci-omap in
kernels from 6.1.x can kill an eMMC.

The change that caused it was reverted in 6.6.87, although the
underlying problem may be something else.

Unfortunately the recently released OpenWrt 24.10.1 has kernel 6.6.86,
and is affected by the bug. I suppose the next OpenWrt service release
will have a newer kernel with the fix applied. So this is just a warning
to people running the current release on omap, and that they may want to
apply the patch.
