QCN6122 wifi in fw-memory-mode 1 has a slightly larger caldb size than
currently defined in the ath11k driver. When coldboot calibration was
disabled, the fw mem mode was changed from 2 (256MB mem profile) to 1
(512MB mem profile), which is the correct setting for devices in scope.
However, in fw mem mode, the caldb size is 0x500000 instead of the max
0x480000 defined in the driver, causing QCN6122 wifi failing to boot:
ath11k b00a040.wifi1: qmi mem size is low to load caldata
ath11k b00a040.wifi1: failed to assign qmi target memory: -22
As such, change the max caldb memory size accordingly.
This macro is used by the driver only as a max size limit to validate
the requested caldb size returned by QMI. Different ath11k wifi chips
have different caldb sizes (for ex. the size for IPQ5018 is 0x200000).

Coldboot calibration does not work causes the firmware to crash during
wifi startup. So let's disable coldboot calibration until a solution is
found.

Add QCN6122 platform support.
QCN6122 is a PCIe based solution that is attached to and enumerated
by the WPSS (Wireless Processor SubSystem) Q6 processor.
Though it is a PCIe device, since it is not attached to APSS processor
(Application Processor SubSystem), APSS will be unaware of such a decice
and hence it is registered to the APSS processor as a platform device(AHB).
Because of this hybrid nature, it is called as a hybrid bus device.
As such, QCN6122 is a hybrid bus type device and follows the same codepath
as for WCN6750.
This is a reversed engineered and heavily simplified version of below
downstream patch:
