By now U-Boot supports Qemu MIPS for little and big endian
as well as 32 bit and 64 bit. Update and fix the example usage
in the README to reflect this.
Signed-off-by: NDaniel Schwierzeck <daniel.schwierzeck@gmail.com>

Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.

For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic
    Could not open option rom 'vgabios.bin': No such file or directory

The 'Limitations & comments' section refers to the
'-m mips' switch which is not valid. The '-m' switch
can be used for setting the virtual RAM size:

    $qemu-system-mips --help | grep '^-m '
    -m megs         set virtual RAM size to megs MB [default=128]
    $

The correct switch for specifying the machine type is '-M'.
Fix the text to refer to that.

Commit fb6a9aab (LCD: display 32bpp decompressed bitmap image)
broke the check that allowed U-Boot to display 8 bpp BMPs on a 16
bpp LCD screen, effectively turning this feature off.

Restore this feature by changing the check back to the same meaning
it originally had.
To avoid future confusion, the check has also been rephrased to make
its meaning clear.

Currently the CLAA WVGA panel is supported, but this panel has to be purchased
separately, so using the DVI output as the default would allow more people to
try the splash screen feature on a mx51evk.

If someone still wants to use the CLAA WVGA, just set the panel variable as:

Since commit de7d02ae (mx6qsabresd: add usdhc2 and usdhc4 support)
SDHC3 device node is no longer 0, which breaks loading a uImage from SDHC3.

Fix it by adapting the default environment to use CONFIG_SYS_MMC_ENV_DEV as the
correct mmc node for loading the kernel from.

While at it, go back to using SDHC3 as the default mmc, since we have Yocto
images that generate an SD card containing U-boot,kernel and rootfs, so it is
more convenient to keep using SDHC3 as it was originally.

We enable console multiplexing and use both serial and LCD for stdout/stderr.
Initially, u-boot output console is observed via serial port.
If you also have a DP panel connected onto your SMDK5250 board,
you can switch to LCD console by typing "setenv stdout lcd".
You can always switch back to serial using "setenv stdout serial".
You can switch error console(stderr) as well, using similar commands.
