Some firmware versions do not support the host capability QMI request.
Since this request occurs before firmware-N.bin and board-M.bin are
loaded, the quirk cannot be expressed in the firmware itself.

The root cause is unclear, but there appears to be a generation of
firmware that lacks host capability support.

Without this quirk, ath10k_qmi_host_cap_send_sync() returns
QMI_ERR_MALFORMED_MSG_V01 before loading the firmware. This error is not
fatal - Wi-Fi services still come up successfully if the request is simply
skipped.

Add a device-tree quirk to skip the host capability QMI request on devices
whose firmware does not support it.

For example, firmware build
"QC_IMAGE_VERSION_STRING=WLAN.HL.2.0.c3-00257-QCAHLSWMTPLZ-1"
on Xiaomi Poco F1 phone requires this quirk.
