Bluetooth: btusb: Some Qualcomm Bluetooth adapters stop working

This issue starts from linux-5.10-rc1, I reproduced this issue on my
Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print
out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and
someone else also reported the similar issue to bugzilla #211571.

I found this is a regression introduced by 'commit b40f58b97386
("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the
patch assumed that if high ROM version is not zero, it is an adapter
on WCN6855, but many old adapters don't need to load rampatch or nvm,
and they have non-zero high ROM version.

To fix it, let the driver match the rom_version in the
qca_devices_table first, if there is no entry matched, check the
high ROM version, if it is not zero, we assume this adapter is ready
to work and no need to load rampatch and nvm like previously.
