ARM: bcm2835: add simplefb DT node during bootz/m

lcd: add functions to set up simplefb device tree
simple-framebuffer is a new device tree binding that describes a pre-
configured frame-buffer memory region and its format. The Linux kernel
contains a driver that supports this binding. Implement functions to
create a DT node (or fill in an existing node) with parameters that
describe the framebuffer format that U-Boot is using.
This will be immediately used by the Raspberry Pi board in U-Boot, and
likely will be used by the Samsung ARM ChromeBook support soon too. It
could well be used by many other boards (e.g. Tegra boards with built-in
LCD panels, which aren't yet supported by the Linux kernel).

cfi_flash: return NULL for invalid base address input
When base address given was out of valid flash address ranges,
flash_get_info() function returned the pointer to the last
element of flash_info[i] array.
This patch changes this function to return NULL pointer
in such a case, which is more correct behaviour.
The function flash_protect_default() calls flash_protect()
immediately after flash_get_info() invocation.
With this correction, flash_protect() function would be
able to return soon, for NULL flash_info.

cfi_flash: Fix unaligned accesses to cfi_qry structure
Packed structure cfi_qry contains unaligned 16- and 32-bits members,
accessing which causes problems when cfi_flash driver is compiled with
-munaligned-access option: flash initialization hangs, probably
due to data error.
Since the structure is supposed to replicate the actual data layout
in CFI Flash chips, the alignment issue can't be fixed in the structure.
So, unaligned fields need using of explicit unaligned access macros.

mtd: nand: use ssize_t instead of size_t to prevent infinite loop
When a all 0xFF buffer is passed to drop_ffs, the no-0xFF check loop
will loop forever.
After the fix, If ssize_t i = -1 and size_t l = i + 1, the value of l
will still be 0 as expected.

nand: adjust erase/read/write partition/chip size for bad blocks
Adjust the sizes calculated for whole partition/chip operations by
removing the size of bad blocks so we don't try to erase/read/write
past a partition/chip boundary.
