Move wavehare epaper shields to conditional Kconfig.
As part of this change, direct drivers Kconfig symbols enabling
(SPI, SSD16XX) are removed as they are application
responsibility. GPIO is removed as well as it should be 'y' by
default on all boards according to Default board configuration
guidelines.
