Add support for SFDP (JESD216B) 4-byte Address Instruction Table. This table is optional but when available, we parse it to get the 4-byte address op codes supported by the memory. Using these op codes is stateless as opposed to entering the 4-byte address mode or setting the Base Address Register (BAR). Flashes that have the 4BAIT table declared can now support SPINOR_OP_PP_1_1_4_4B and SPINOR_OP_PP_1_4_4_4B opcodes. Tested on MX25L25673G.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
