nand: raw_nand: fix timeout issue in nand_wait_ready
...
nand_wait_ready is called with a millisecond delay
but the timeout used a micro second. Fixing the conversion
in the timeout call.
The prototype of the function is also changed to use an unsigned int
parameter.

Add SPI-NOR framework
...
SPI-NOR framework is based on SPI-MEM framework using
spi_mem_op execution interface.
It implements read functions and allows NOR configuration
up to quad mode.
Default management is 1 data line but it can be overridden
by platform.
It also includes specific quad mode configuration for
Spansion, Micron and Macronix memories.

Add SPI-NAND framework
...
This framework supports SPI-NAND and is based on the
SPI-MEM framework for SPI operations. It uses a common high
level access using the io_mtd.
It is limited to the read functionalities.
Default behavior is the basic one data line operation
but it could be overridden by platform.

Add SPI-MEM framework
...
This framework supports SPI operations using a common
spi_mem_op structure:
- command
- addr
- dummy
- data
The framework manages SPI bus configuration:
- speed
- bus width (Up to quad mode)
- chip select

Add raw NAND framework
...
The raw NAND framework supports SLC NAND devices.
It introduces a new high level interface (io_mtd) that
defines operations a driver can register to the NAND framework.
This interface will fill in the io_mtd device specification:
- device_size
- erase_size
that could be used by the io_storage interface.
NAND core source file integrates the standard read loop that
performs NAND device read operations using a skip bad block strategy.
A platform buffer must be defined in case of unaligned
data. This buffer must fit to the maximum device page size
defined by PLATFORM_MTD_MAX_PAGE_SIZE.
The raw_nand.c source file embeds the specific NAND operations
to read data.
The read command is a raw page read without any ECC correction.
This can be overridden by a low level driver.
No generic support for write or erase command or software
ECC correction.
NAND ONFI detection is available and can be enabled using
NAND_ONFI_DETECT=1.
For non-ONFI NAND management, platform can define required
information.
