Make the support for 4K subpage I/O on a SPI NOR flash configurable.
A board which requires the SPI NOR to be accessed in larger 32KiB
or 64KiB pages can disable the 4K subpage support, but by default,
the support for 4K subpage I/O is enabled. The functionality of this
option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux.
This is extremely useful in case one uses UBI on a SPI NOR flash.
UBI needs at least 15k EBs and can not work on a flash which uses
4k ones, so disabling the support for 4k subpages lets UBI work on
such flash.

The default boot command searches for dofastboot varaiable
and does a fastboot if it is set to 1.
But the condition "if test ${dofastboot} -eq 1" always
returns true if dofastboot is not defined and breaking mmc boot.
So make dofastboot as 0 by default and let the runtime
environment set it if fastboot is required.

This reverts commit 5b34436035.
This function has a few problems. It calls fdt_parent_offset() which as
mentioned in code review is very slow.
https://patchwork.ozlabs.org/patch/499482/https://patchwork.ozlabs.org/patch/452604/
It also happens to break SPI flash on Minnowboard max which is how I noticed
that this was applied. I can send a patch to tidy that up, but in any case
I think we should consider a revert until the function is better implemented.

Remove FAT function prototypes from the cm5200 firmware update code, and

This exposes the fact that the custom prototyoe for do_fat_read() in

do_fat_read() with fat_exists(). This removes the only use of
do_fat_read() outside of the FAT code.
