It seems that Micron MTFC4GACAJCN-1M despite advertising TRIM support does
not work when the core is trying to use REQ_OP_WRITE_ZEROES.
We are seeing the following errors in OpenWrt under 6.1 on Qnap Qhora 301W
that we did not previously have and tracked it down to REQ_OP_WRITE_ZEROES:
[ 18.085950] I/O error, dev loop0, sector 596 op 0x9:(WRITE_ZEROES) flags 0x800 phys_seg 0 prio class 2
Disabling TRIM makes the error go away, so lets add a quirk for this eMMC
to disable TRIM.

Let's leave this another week or so, to allow Micron folkz to confirm
before applying.

Thanks, I have sent the patch for one of Kingstom eMMC as well that
seems to have TRIM broken
as well.
