arch/arm/src/imxrt: May eDMA channel linking a configuration option. Add support to select the DMA channel priority and pre-emption controls.
arch/arm/src/imxrt: Update some HowTo comments in the eDMA header file.
arch/arm/src/imxrt: Fix a logic error in parmater passing. Caller does not know actual channel number when setting up linked channel, only the channel handler.
arch/arm/src/imxrt: Fixes for clean eDMA driver build with Scatter/Gather enabled.
arch/arm/src/imxrt: Fixes for clean eDMA driver build with Scatter/Gather disabled.

arch/arm/src/imxrt: Replacing some of the logic cloned from SAMv7 XDMAC with eDMA logic from NXP sample code. I am thinking that the eDMA is too complex to force into the same pattern as for other MCUs.
arch/arms/src/imxrt/imxrt_edma.c: Add support for in-memory TCDs.
arch/arm/src/imxrt/chip: Add an in-memory representation of the TCD in imxrt_edma.h
imxrt_gpioirq.c
- Add check for interrupt mask register before dispatching ISR. The GPIO_ISR bits are set independent of the GPIO_IMR bits.
imxrt_irq.c
- fixed a range check for extint in function imxrt_irqinfo().
This port was the joing effort of Janne Rosberg, Ivan Ucherdzhiev, and myself. I give credit to Ivan for the kill because he is the one to held on to the end.
Squashed commit of the following:
Author: Gregory Nutt <gnutt@nuttx.org>
configs/imxrt1050-evk/scripts: Add section to linker script to handle the case where RAMFUNCs are enabled. RAMFUNCs appear to be enabled in the default configuration ... they probably should not be enabled.
Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>
arch/arm/src/imxrt: imxrt_lowputc.c is finished. Now everything needed for the initial port is done and ready for testing.
