Use a generic 'dram_vals[]' array that has the full initialization
sequence and rename the initialization method so it doesn't has a
frequency on its name.

The MXS SPL didn't mark local functions "static". Fix it. This also makes the
SPL smaller by roughly 300 bytes.

Implement common function to setup the VDDIO, VDDD and VDDA voltage.
Right now, there are two almost identical functions to setup VDDIO
and VDDD, which is prone to breakage. Pull out the differences into
constant structure and pass them as an argument to the common function.
Moreover, the function has almost identical loops for setting higher
and lower VDDx voltage. Merge these two loops.

The i.MX23 has different register layout and bit placement in the
power supply. Thus, in order to be able to add support for MX23,
rename the MX28's regs-power.h to regs-power-mx28.h . Moreover,
add ifdef around inclusion of regs-*-mx28.h in imx-regs.h so the
MX23 boards will include proper set of registers.

These registers don't have _SET, _CLR and _TOG at the respective offsets
available, these registers has to be toggled via R-M-W if needed. Thus do

The mx5 lowlevel_init.S contains board-specific code based on the reference
design. Let's keep it since it avoids creating new lowlevel_init files and it
may be used by many boards. But add a config to make it optional in order not to
cause issues on boards not following this part of the reference design.

A custom board_ehci_hcd_init() may be unneeded, so add a weak default

commit 199adb601ff34bdbbd0667fac80dfe0a87bffc2b "common/misc: sparse
fixes" broke the help command trying to fix the sparse error
"command.c:44:38: error: bad constant expression".
As Henrik points out, the fix was bad because the commit used
CONFIG_SYS_MAXARGS whereas the code intended to use the maximum
number of commands (not arguments to a command).
Revert command.c changes to the original code as asked by Wolfgang.
