lsxl: place the dtb below the inital ramdisk

The dtb was loaded at a memory address after the initial ramdisk. Thus a
large ramdisk would overwrite the dtb. Move it to "ramdisk_start - 64k".
64k should be enough for the device tree blob. Also the kernel
documentation arm/Booting suggests to put the dtb before the initial

mx53loco: Fix boot hang during reboot stress test

Currently by running the following test:

=> setenv bootcmd reset
=> save
=> reset

, we observe a hang after approximately 20-30 minutes of stress reboot test.

Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.

MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":

"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."

According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:

"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"

So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.

With this change applied the board has gone through three days of reboot stress
test without any hang.

arc: build libgcc in U-Boot

This way we may have very limited set of functions implemented so we
save some space.

Also it allows us to build U-Boot for any ARC core with the same one
toolchain because we don't rely on pre-built libgcc.

For example:
 * we may use little-endian toolchain but build U-Boot for ether
endianess
 * we may use non-multilibbed uClibc toolchain but build U-Boot for
whatever ARC CPU flavour that current GCC supports

Private libgcc built from generic C implementation contributes only 144
bytes to .text section so we don't see significant degradation of size:
--->8---
$ arc-linux-size u-boot.libgcc-prebuilt
   text    data     bss     dec     hex filename
 222217   24912  214820  461949   70c7d u-boot.libgcc-prebuilt

 222361   24912  214820  462093   70d0d u-boot.libgcc-private
--->8---

Also I don't notice visible performance degradation compared to
pre-built libgcc (where at least "*div*" functions are had-written in
assembly) on typical operations of downloading 10Mb uImage over TFTP and
