Instead of reading the silicon version from ROM, we should
read the SREV register from the IIM.
Freescale has dropped all support for MX51 REV1.0, only MX51
REV 2.0 and 3.0 are valid.

Currently, only two operating points: 160Mhz and 800Mhz.
the operating points are tested on babbage 3.0

This has the addional effect that the macros CSCR_U, CSCR_L and CSCR_A
are not used anymore in mach-pcm038.c and mach-qong.c. These still use
the deprecated IO_ADDRESS macro and shouldn't be used in new code.

We had hardcoded cpu_is_ macros for mxc architectures till now. As we
want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_
macros which expand to 0 or 1 if only one architecture is compiled in and
only check for the cpu type if more than one architecture is compiled
in.

* define new CONFIG_ARCH_MX21 (this one is currently mutually exclusive to
CONFIG_ARCH_MX27, but this might change)
* splits one header file. Memory definitions, interrupt sources,
DMA channels are split into common part, i.MX27 specific and i.MX21
specific.
* guard access to UART5/UART6, which don't exist on i.MX21

* adds Kconfig variables
* specifies different physical address for i.MX21 because of the
different memory layouts
* disables support for UART5/UART6 in the i.MX serial driver
(the i.MX21 doesn't have those modules)

This adds macros to get CSCR upper, lower and additional registers.
These registers are needed to configure a chip select line. The offset
layouts of these Registers are identical on mx27 and mx31, hence we can
use the macros in generic way
