[U-Boot] [PATCH 1/3 v6] arm926ejs: add NXP LPC32x0 cpu series support

[Marek Vasut <marek.vasut@gmail.com>]

> This change adds initial support for NXP LPC32x0 SoC series.
> 
> Signed-off-by: Vladimir Zapolskiy <vz@mleia.com>
> ---
> Changes from v5 to v6:
> * replaced some spaces with tabs in macro declarations
> * more rules separating 14-clock and ns16650 UARTs in config.h
> 
> Changes from v4 to v5:
> * corrected address in GPLv2+ licence header in files
> 
> Changes from v3 to v4:
> * extended memory controller definitions are introduced
> * added print_cpuinfo() function
> 
> Changes from v2 to v3:
> * checkpatch.pl reports zero errors and warnings
> 
> Changes from v1 to v2:
> * BIT(n) and SBF(s, v) macro are not used anymore
> * removed NS16550 and 14-clock UART definitions from uart.h
> * added devices.c file, which contains standard UART preinitialization
> routine * added get_serial_clock() function, it returns actual frequency
> of UART clock * __udelay() realization is simplified, no need of interrupt
> handling
