mxs: spl_mem_init: Align DDR2 init with FSL bootlets source

Currently the following kernel hang happens when loading a 2.6.35 kernel from
Freeescale on a mx28evk board:

RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
Bus freq driver module loaded
IMX usb wakeup probe
usb h1 wakeup device is registered
mxs_cpu_init: cpufreq init finished
...

Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01
package, the hang does not occur.

Comparing the DDR2 initialization from the bootlets code against the U-boot
one, we can notice some mismatches, and after applying the same initialization
into U-boot the 2.6.35 kernel can boot normally.

Also tested with 'mtest' command, which runs succesfully.

imx-common: timer: fix 32-bit overflow

The i.MX6 common timer uses the 32-bit variable tbl (time base lower)
to record the overflow of the 32-bit counter. I.e. if the counter
overflows, the variable tbl does overflow, too.

To capture this overflow, use the variable tbu (time base upper), too.
Return the combined value of tbl and tbu.

lastinc is unused then, remove it.

mx28evk: Disable CONFIG_CMD_I2C

When loading a Freescale 2.6.35 on a mx28evk the following issue is seen:

sgtl5000_hw_read: read reg error : Reg 0x00
Device with ID register 0 is not a SGTL5000

Disabling CONFIG_CMD_I2C makes the sgtl5000 probe to succeed.

Mainline kernel does not show this problem.

Until the real cause is not identified, disable 'CONFIG_CMD_I2C' for the
time being.
