Change Cadence i2c and Zynq GPIO from modules to built-in drivers (#3821)

On Kria KD240 slg7xl45106 device is handling reset for USB hub which is
providing access to SD card (USB/SD converter). Access to this device is
done via i2c which needs to be also enabled in the kernel as built-in
driver not as module when rootfs is mounted.

Also change ZYNQ_GPIO to be built-in driver because i2c is using gpio for
bus recovery that's why it should be also enabled to probe i2c driver
properly.

v6.6 kernel doesn't have support for usb5744 driver that's why disable it
but add TODO to enable it once v6.12 upgrade is done.
