drivers: flash: spi_nor: support 32-bit addresses in access method

Support both 24-bit and 32-bit address values when constructing the
device command.  Note that some commands require 24-bit address
regardless of mode, and some require 32-bit addresses regardless of
mode, so provide command-specific overrides of a generic (but not yet
configurable) default address size.

With this we no longer need a special interface for READ_SFDP which
uses a 24-bit address but with a wait state introduced by clocking out
a fifth command byte.
