Add functionality to read and parse SFDP parameters to auto-detect
flash size, page size and address width of flash. This enables
flash access above 16MB using 4-byte addressing mode.

Add driver support to get SFDP information of flash and use it to
access flash above 16MB.

Enable reading and parsing of SFDP parameters for Spansion's
s25fs512 flash to auto-detect its size, its page size and the
addressing mode it supports.
