Adds board support for the Teensy LC board. Support is based off the Freedom KL25Z board. LED, PWM, and UART0 have been tested. The SPI pins are mapped correctly but have not yet been tested. From Michael Hope as SourceForge patch 51.

Teensy LC README
================
This is the README file for NuttX on the Teensy LC. The Teensy LC
is a DIP style breakout board for the MKL25Z64 and comes with a USB
based bootloader.
Development Environment
=======================
All testing was done with the GNU ARM Embedded 4.9 toolchain on
Linux. See https://launchpad.net/gcc-arm-embedded to download.
Once you've configured and built NuttX, flash the resulting
nuttx.hex file to the board using the Teensy Loader Application.
LEDs
====
The Teensy LC has a single LED. If CONFIG_ARCH_LEDS is defined, then
NuttX will update the LED as the board boots. The summary is:
* LED off: board booting
* LED on: initial stack created
* LED flashing: panic.
See `include/board.h` for details.
Serial Console
==============
The serial console is mapped to UART0 and appears on pins 0 (RX) and
1 (TX). Consider using a 3.3 V USB to serial adapter such as the
Sparkfun #9717 FTDI cable.

* pins.
* 2. Provide kl_spi[n]select() and kl_spi[n]status() functions
* in your board-specific logic. These functions will perform chip
* selection and status operations using GPIOs in the way your board
* is configured.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* kl_spi[n]cmddata() functions in your board-specific logic. These
* functions will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call to up_spiinitialize() in your low level application
* initialization logic
* 4. The handle returned by up_spiinitialize() may then be used to bind
* the SPI driver to higher level logic (e.g., calling

*
* An alternative way to program the PIO chip select pins is as a normal
