Add support for LPC40xx family chips
* Corrected a few peripheral definitions and pin functions for the LPC17xx family.
Added configuration options, chip definitions, and additional pin functions for the LPC40xx family.
Added board configurations for Embedded Artists LPC4088 Quickstart board and LPC4088 Developer's kit. These configurations are still something of a work in progress. In particular, the LCD functionality is untested.
* First pass rename in *.c and *.h files.
* Renamed LPC17XX to LPC17XX_40XX in config files
* Rplaced LPC17xx with LPC17xx/LPC40xx in .c files
* Replaced LPC17xx with LPC17xx/LPC40xx in .h files
* Updated some documentation
* Working on moving directories
* moved arch/arm/src/lpc17xx and arch/arm/include/lpc17xx to lpc17xx_40xx
* Renamed LPC17_* constants / configuration options to LPC17_40_*
* Updated chip family name defines
* Renamed some chip-specific files
* Updated references to renamed files
* Updated references to lpc17_ to lpc17_40_
* Renamed source files from lpc17_* to lpc17_40_*
* Clean up white space

drivers/lcd/tda19988.c: Now uses the new common videomode structure of include/nuttx/video/videomode.h as do other video components.
video/, include/nuttx/video/videomode.h: Separate EDID and from videomode managment. They really are separate things.
back at physical address 0x2007C000 and 0x20080000 (i.e. right below and right
above a 512 KiB boundary). Memory from those two blocks is considered
continuous when assigned to a heap.
In the protected build mode, when the memory protection unit is used, though,
it must be split into two MPU regions. This is because MPU regions must be
naturally aligned, and the 32KiB continuous address space of the two 16KiB AHB
SRAM blocks does not start at an address divisible by 32KiB.
The only other configurations that use protected build mode on lpc17xx are
currently open1788/knsh and open1788/knxterm. The LPC1788 has the AHB SRAM
blocks mapped more sanely (from an MPU region point of view), which is
probably why no problems emerged here. Both still compile with my change and
other than wasting an MPU region (which would otherwise remain unused) should
work fine. That said, I have no hardware to confirm.
arch/arm/src/am335x: Add logic to map the framebuffer to a non-cached, non-buffered memory region.
arch/arm/src/am335x: Remove struct am335x_fbinfo_s. Replaced with configuration settings that provide the same information.

arch/arm/src/am335x/am335x_lcdc.c: LCD driver now compiles.
arch/arm/src/am335x/am335x_lcd.c: This brings the LCD driver to code complete. Have not yet attempted to compile.
arch/arm/src/am335x/am335x_edid.c: Framebuffer is pre-allocated. In verification of video mode, include a test to assure that the video mode can be supported by the pre-allocated framebuffer memory.
arch/arm/src/am335x/am335x_lcd.c: At a little bit of LCD initialization logic. There is a long way to go.
arch/arm/src/am335x/am335x_edid.c: Add am335x_lcd_videomode() which provides an alternative way of initializing the LCD controller.
arch/arm/src/am335x/am335x_edid.c: edit.h has move to include/nuttx/video.
arch/arm/src/am335x/hardware/am335x_cm.h: Fix a typo in a macro name.
arch/arm/src/am335x/am335x_edid.c: Integrate video/edid support.
arch/arm/src/am335x/am335x_edid.c: Fall back to VGA mode is not valid videomode is availabe in the EDID data.
arch/arm/src/am335x/am335x_edid.c: Fixes for a partially clean compile.
arch/arm/src/am335x/am335x_edid.c: Add basic logic to convert EDID montor descriptions into a form usable for LCD configuration.
arch/arm/src/am335x: Add framework (only) for an LCD driver. Initial commit is simply the LPC54 framebuffer driver with naming changes.

arch/arm/src/tiva: Add a workaround for tiva with qemu
With qemu, tiva_ifup() hangs because ethernet link status can not
be set correctly. This PR is a workaround to avoid this issue.

Squashed commit of the following:
configs/makerlisp/scripts/makerlisp_ram.linkcmd: Fixup .RESET and .STARTUP. These need to be redirected to RAM since they default to ROM.
configs/makerlisp/scripts/makerlisp_ram.linkcmd: Restore some settings that should be unnecessary but are really required by the current implementation.
configs/makerlisp: Rename nsh configuratinon to nsh_flash. Create new configuration, nsh_ram, that is identical to the nsh_flash configuration except that the code runs out of external SRAM.
configs/makerlisp/scripts: Add a linker script to support execution from RAM.
