Commit c71a77ab8 (ns16550: switch to resource) has introduced generic
read/write access to 16550 register and a 'shift' parameter to allign
register index to physicall registers.
The correct 'shift' value was missing in all omap based boards.
Corrected this to 2 which has fixed the problem.
Tested on a PCM-049 phyCORE-OMAP4 board.

Keep frequency multiplier enabled to be able to do a warmstart
The wachtdog's reset does only reset the ARM core, not the whole silicon.
But the PLLs seems to do some strange things: It seems they switch back to
the low frequency reference when the watchdog barks. But in the case the
frequency multiplier is off (not used due to 26 MHz reference usage) the
machine stops, because the PLLs are stopping due to the lack of a reference
frequency. As the power on reset will set the FPM_EN bit again, a power cycle
brings the machine back to life.
By keeping the frequency multiplier enabled, also a warmstart triggered by the
watchdog can restart the machine now.

Updated mx53 ddr3 script in order to align with the latest Freescale version from July 8, 2011:
-change ESDREF[REF_SEL]=01 (for 32KHz), from incorrect setting of 00 (64KHz)
-change DDR3 MR0 write to "setmem /32 0x63fd901c = 0x052080b0" from "0x092080b0".
This changes write recovery from 8 clocks to 6 clocks(in line with ESDCFG1[tWR])

These images have to be located in the first 128MB of SDRAM, so
use the following strategy:
- first try to map the image. If the pointer is within the first
128MB of sdram everything is fine.
- if we can't map the image, check for SDRAM being smaller than
128MB we can use malloc for allocating space for the image.
- As a last fallback we simply put the image to 8MB into SDRAM.
This is not very clean. We try our best by checking that we
won't overwrite the malloc space.

Some older pcm043 only work correct when cpu frequency is set up
to 399MHz. All modules with revision >= 1315.4 are equipped
with a i.MX35 TO2.1 and do run with 532MHz.
