Changing PLL settings is somehow tricky on the i.MX27: Whenever the clock
speed of the main PLL is changed, the clock stops for about 100 us until the
PLL locks into the new frequency. While this clock stop, also the SDRAM
controller cannot refresh the memory, because it uses the same clock source.
This can lead into data loss and random system crashes.
This patch divides the PLL setting in two steps. First step is to re-program
the PLL and clock settings to values possible at a core supply of 1.25 V.
Second step is to increase the core power supply to 1.45 V and switch the
CPU clock to the specified 400 MHz.

Guessing the size of an attached harddisk (access via x86 BIOS) was needed
due to the fact, barebox can't query this information from the BIOS easily.
But with the SD/MMC cards, there will be a second user of the generic disk
handling routines. And with this media it is very easy to know its size.
This patch provides a workaround to keep the guessing feature if the size of
the registered disk is 0. If it is not 0, the given value will be used instead.
Note: This is in preparation to add MCI card support, which can be handled
like a disk drive.

Until now, the main function of the sandbox port wants to use the libc
getopt(), but as we have a getopt() implementation in barebox as well,
it is silently used instead. This works in the usual case, but if an
error occurs (i.e. by using an unknown argument) in getopt(), the
implementation tries to write to the console, which is not initialized
and thus breaks with a null pointer exception.
This patch changes the main function to use getopt_long() instead of
getopt(). This makes us use the implementation in glibc and while being
there, we get long options, which makes us look more professional...
