Fixes a bug found on thuban boards, which were for 2 years in
a long-term test with varying temperatures. They showed
problems in u-boot when attaching the ubi partition:
U-Boot# run flash_self_test
Booting from nand

UBI: scanning is finished

Reason is, that accidentially the U-Boot implementation
from __schedule_ubi_work() did not check the flag
ubi->thread_enabled and started with wearleveling work,
but ubi did not have setup all structures at this point
and crashes.
Solve this problem by splitting work scheduling and processing.

Xilinx changes for v2018.03
- Several Kconfig fixes (also moving configs to defconfigs)
- Some DTS updates
- ZynqMP psu rework based on Zynq concept
- Add low level initialization for zc770 and zcu102
- Add support for Zynq zc770 x16 nand configuration

The Arasan NFC driver requires the self-init mode,
so it should select it.
Instead of having the config header define the macro,
it's cleaner to select the option at the Kconfig level.

The variable cfi_flash_num_flash_banks is defined iff
CONFIG_SYS_MAX_FLASH_BANKS_DETECT is defined, but it is used
unconditionally in the function cfi_flash_init_dm. This leads to a
undefined variable compile error when CONFIG_SYS_MAX_FLASH_BANKS_DETECT
is not defined, but DM is enabled.
Fix this by always defining the cfi_flash_num_flash_banks variable.

In a while loop in cfi_flash.c the array "start" is accessed at the index
"sector" before the index variable "sector" is bounds-checked, which
might lead to accesses beyond the bounds of the array.
Swap the order of the checks in the "&&" expression, so that the
short-circuit evaluation prevents out-of-bounds array accesses.

mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.
