ipq807x: 6.1: fix I/O WRITE_ZEROES errors on some eMMC devices

Linux 5.19 added a feature where if there is TRIM support being advertised
on eMMC kernel will use TRIM to offload erasing to zero.

However, like always there are eMMC IC-s that advertise TRIM and kind of
work but trying to use TRIM for offloading will cause I/O errors like:
[   18.085950] I/O error, dev loop0, sector 596 op 0x9:(WRITE_ZEROES) flags 0x800 phys_seg 0 prio class 2

So, lets utilize the kernel MMC quirks DB to disable TRIM for eMMC models
that are known to cause this.

This will fix the WRITE_ZEROES error on:
Qnap 301W which uses Micron MTFC4GACAJCN-1M
Zyxel NBG7815 which uses Kingston EMMC04G-M627
