Kate Wang d628bfc148 drivers: mipi_dsi: dsi_mcux_2l: Use NXP DCNano DBI driver for memory write
There is no smartdma on RT700, so to perform DCS memory write the CPU has
to write APB buffer word by word, which is too slow for most applications.
But the DCNano in DBI mode can be used to interface with the MIPI-DSI on
RT700, and send data to MIPI-DSI to transfer, once it is properly
configured, which solves the issue.
First added new parameter first_write in display_buffer_descriptor to let
NXP DCNano DBI driver know to use MIPI_DCS_WRITE_MEMORY_START or
MIPI_DCS_WRITE_MEMORY_CONTINUE.
Second updated the MCUX MIPI-DSI driver to support using the NXP DCNano DBI
driver for memory write.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
