ARM: i.MX: Remove old boards

This removes a bunch of old boards that nobody showed interest in
for a long time:

Freescale boards
================
MACH_IMX21ADS
MACH_IMX27ADS
MACH_FREESCALE_MX25_3STACK
MACH_FREESCALE_MX35_3STACK
MACH_FREESCALE_MX53_SMD

Eukrea boards
=============
MACH_EUKREA_CPUIMX25
MACH_EUKREA_CPUIMX27
MACH_EUKREA_CPUIMX35
MACH_EUKREA_CPUIMX51SD

Garz+Fricke boards
==================
MACH_NESO
MACH_GUF_CUPID

Phytec boards
=============
MACH_PCM037
MACH_PCM043

Amazon boards
=============
MACH_KINDLE3

All these boards have not been converted to device tree nor do they
support multi-image generation. As they are becoming a maintenance
burden remove them now.

A board can always be added back once it is ported to support the
recent barebox interfaces.
