Fix USB not working on Pi4 Dev Image

[3rdIteration]

As it stands, USB doesn't work on the existing Pi4 dev image. (Easy to verify with a USB keyboard) This is easily fixed by enabling some additional kernel options. (And also removing some other unnecessary stuff which leads to a kernel panic if left enabled)

The following Changes are included in this PR: *Enabled required kernel modules for USB on Pi4 (It is connected via the PCI bus, which is very different from other Pi models) *Disable some other kernel modules that aren't required (And are disabled on other profiles)
