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.
