in the Reference Manual) allows Direct Memory Access transfers

improve the common clock support code for MPC512x
- expand the CCM register set declaration with MPC5125 related registers
(which reside in the previously "reserved" area)
- tell the MPC5121, MPC5123, and MPC5125 SoC variants apart, and derive
the availability of components and their clocks from the detected SoC
(MBX, AXE, VIU, SPDIF, PATA, SATA, PCI, second FEC, second SDHC,
number of PSC components, type of NAND flash controller,
interpretation of the CPMF bitfield, PSC/CAN mux0 stage input clocks,
output clocks on SoC pins)
- add backwards compatibility (allow operation against a device tree
which lacks clock related specs) for MPC5125 FECs, too
telling SoC variants apart and adjusting the clock tree's generation
occurs at runtime, a common generic binary supports all of the chips
the MPC5125 approach to the NFC clock (one register with two counters
for the high and low periods of the clock) is not implemented, as there
are no users and there is no common implementation which supports this
kind of clock -- the new implementation would be unused and could not
get verified, so it shall wait until there is demand

reword the clock control module's registers declaration such that the
MCLK related registers form an array and get indexed by PSC controller
or CAN controller component number
this change is in preparation to COMMON_CLK support for the MPC512x
platform, the changed declaration remains neutral to existing code since
the PSC and MSCAN CCR fields declared here aren't referenced elsewhere

- implement all of the init, init early, and setup arch routines in the
shared source file for the MPC512x PowerPC platform, and make all
MPC512x based boards (ADS, PDM, generic) use those common routines
- remove declarations from header files for routines which aren't
referenced from external callers any longer
this modification concentrates knowledge about the optional FSL DIU
support in one spot within the shared code, and makes all boards benefit
transparently from future improvements in the shared platform code
the change does not modify any behaviour but preserves all code paths

Fix warnings:
symbol 'clockctl' was not declared. Should it be static?
symbol 'rate_clks' was not declared. Should it be static?
symbol 'dev_clks' was not declared. Should it be static?
symbol 'mpc5121_clk_init' was not declared. Should it be static?

Add ability to configure chip select (CS) parameters for devices
that need different CS parameters setup after their configuration.
I.e. an FPGA device on LP bus can require different CS parameters
for its bus interface after loading firmware into it. A driver
can easily reconfigure the LPC CS parameters using this function.

MPC5121 DIU configuration/setup as initialized by the boot
loader currently will get lost while booting Linux. As a
result displaying the boot splash is not possible through
the boot process.
To prevent this we reserve configured DIU frame buffer
address range while booting and preserve AOI descriptor
and gamma table so that DIU continues displaying through
the whole boot process. On first open from user space
DIU frame buffer driver releases the reserved frame
buffer area and continues to operate as usual.
