board: sl28: fix RGMII clock and voltage

It was noticed that the clock isn't continuously enabled when there is
no link. This is because the 125MHz clock is derived from the internal
PLL which seems to go into some kind of power-down mode every once in a
while. The LS1028A expects a contiuous clock. Thus enable the PLL all
the time.

Also, the RGMII pad voltage is wrong, it was configured to 2.5V (that is
the VDDH regulator). The correct voltage is 1.8V, i.e. the VDDIO
regulator.

One of the points of putting the rescue boot command into default
environment is that user can invoke it without physical access to the
board (without having to press the factory reset button), by running
  run bootcmd_rescue
in U-Boot's console.

Therefore we have to ensure that bootcmd_rescue is always set to default
value, regardless of whether the factory reset button was pressed.
Otherwise the variable will be empty for example after upgrade from

fs/squashfs: fix reading of fragmented files

The fragmented files were not correctly read because of two issues:

- The squashfs_file_info struct has a field named 'comp', which tells if
the file's fragment is compressed or not. This field was always set to
'true' in sqfs_get_regfile_info and sqfs_get_lregfile_info. It should
actually take sqfs_frag_lookup's return value. This patch addresses
these two assignments.

- In sqfs_read, the fragments (compressed or not) were copied to the
output buffer through a for loop which was reading data at the wrong
offset. Replace these loops by equivalent calls to memcpy, with the
right parameters.

I tested this patch by comparing the MD5 checksum of a few fragmented
files with the respective md5sum output in sandbox, considering both
compressed and uncompressed fragments.

But since the pci-aardvark.c driver enables Link Training just a few lines

PCIE_CORE_LINK_TRAINING does not actually enter Recovery state at this
