feat(nand): count bad blocks before a given offset

In case of FIP, the offsets given in the FIP header are relative.
If bad blocks are found between the FIP base address and this offset,
the offset should be updated, taking care of the bad blocks.

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.
