Before 6.13, random seed to the firmware was given based on the logic
whether the device had valid OTP or not, and such devices were found
mainly on the T2 and Apple Silicon Macs. In 6.13, the logic was changed,
and the device table was used for this purpose, so as to cover the special
case of BCM43752 chip.

During the transition, the device table for BCM4364 and BCM4355 Wi-Fi chips
which had valid OTP was not modified, thus breaking Wi-Fi on these devices.
This patch adds does the necessary changes, similar to the ones done for
other chips.
