PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.
By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

This is a more appropriate symbol naming for an image copy & relocate feature,

In the current u-boot, the device pin multiplexing and clock
initialisation needs to be early during the boot process and before
board_init() is called. U-boot is currently crashing on this board
because this is not being done early enough. Therefore, add a s_init()
function for the omap5912-osk board to do this.
Also fix the stack pointer so that it is pointing to the end of the
internal RAM and not the beginning as this was also causing the device
to crash.

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.
