This patch set adds minimal support for the LPC18xx/43xx family of
Cortex-M3/4 MCUs from NXP.
Patch set is based on Linus master v4.1-rc1. I would be greaet if
these patches could go into 4.1.
To keep the amount of dependencies down the PLL1 clock has been hard
coded in the lpc18xx.dtsi file. The clock system of LPC18xx is quite
advanced for a MCU and requires two clk drivers to work. A patch set
with these drivers and update to the dtsi files will be posted
separately.
Drivers for pinctrl, gpio, ethernet, i2c, rtc and emc (external
memories) are also coming for LPC18xx. Right now these can found on:

Sucessfuly tested on Embedded Artist LPC4357 Developers Kit.
Changes since v1:
- use generic soc match strings in board-dt
- remove armv7m reset in board-dt (this wasn't working and a proper
reset driver is coming)
- move dt aliases to board files
- add support for Hitex LPC4350 eval board from Ariel D'Alessandro
- rename lpc3250-timer to lpc3220-timer to match lpc32xx.dtsi
- add ea (and hitex) to vendor-prefixes
- rename lpc4357-ea4357 to lpc4357-ea4357-devkit
- add lpc32xx_read_sched_clock from Ezequiel Garcia
- use named clk in lpc3220 clocksource driver
- rebase on 4.1-rc1
