Gunar Schorcht 04c3facd8e drivers/lcd: add MCU 8080 8-/16-bit parallel mode support
For the parallel interface support the following changes were made:

1. Additional `lcd_*` pseudomodules are defined to control whether SPI serial or MCU 8080 8-/16-bit parallel interface is used.
2. The low level function implementation was extended for parallel interfaces so that the now can use either the SPI serial interface or the MCU 8080 8-/16-bit parallel interface.

Using the `lcc_*` modules, either the SPI serial interface or the MCU 8080 8-/16-bit interface or even both for multiple display can be used simultaneously.

help
Enable this configuration to convert little endian colors to big endian.
LCD device requires colors to be send in big endian RGB-565 format.
Enabling this option allows for little endian colors. Enabling this
however will slow down the driver as it cannot use DMA anymore.
