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

Backport newly released firmware blobs from linux-firmware commit
d52556e4592e64023157a83fb0f483661f23ac0e. `git cherry-pick` works for
each target branch, but the generated patch doesn't apply to each other.
B/C/D would requires this explicitly and Eoan should be rebased onto
linux-firmware master branch HEAD as usual.

[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. For others, they have been verified individually on the
platforms that have corresponding hardwares.
