mfd: ezx-pcap: Remove unused driver

Support for the Motorola EZX phones based on Intel PXA processors was removed in 2022, but this driver remained present in the tree. As far as I can tell, the support was never quite functional upstream because the board files did not actually instantiate the SPI device for the PCAP. There are still also drivers for the various mfd cells: keys, touchscreen, regulator and rtc, all of which are obviously orphaned as well but can be removed separately as the Kconfig dependency now prevents them from being enabled.
