interconnect: qcom: rpm: make QoS INVALID default

Currently NOC_QOS_MODE_FIXED is defined as 0x0 which makes it the
default option (partial struct initialization). The default option
however should be NOC_QOS_MODE_INVALID.

That results in bogus QoS configurations being sent for port 0 (which
is used for the DRAM endpoint on BIMC, for example) coming from all nodes
with .qos.ap_owned = true and uninitialized .qos.qos_mode. It's also an
issue for newer SoCs where all nodes are treated as if they were ap_owned,
but not all of them have QoS configuration.

The NOC_QOS_MODEs are defined as preprocessor constants and are not used
anywhere outside qcom_icc_set_noc_qos(), which is easily worked around.
Separate the desc->type values from the values sent to msmbus in the
aforementioned function. Make the former an enum for better mainainability.
