[Impact]
Bluetooth on Intel Wireless-AC 9462 on IceLake requires new firmware
blobs intel/ibt-19-32-0.{sfi,ddc} to be enabled.

[Fix]
Backport newly released firmware blobs from linux-firmware commit
d52556e4592e64023157a83fb0f483661f23ac0e. Note this commit also updates
firmware files for others in the AX201 family, but only the necessary
ones are backported in this SRU to minimize potential impact.

[Test Case]
Verified with hardware platforms with corresponding devices. Completely
power off and power on to trigger firmware reload, check from dmesg to
see if Bluetooth firmware has been correctly loaded.

[Regression Risk]
Low. This adds new binary firmware blobs that are only loaded by target
configuration.

Other blobs in the original commit were also tested but are out of the
scope here.
