Add support for negotiating the highest possible pixel mode (from single, dual, quad) with the Cadence CSI2RX bridge. This is required to drain the Cadence stream FIFOs without overflowing when the source is operating at a high link-frequency [1]. Also, update the Kconfig as this introduces a hard build-time dependency on the Cadence CSI2RX driver, even for a COMPILE_TEST.
