Add a generic flash driver, which is used when we don't find a matching
flash in our database. All the basic features of a flash can be discovered
by SFDP and most (if not all) newer flashes support it.

changes since v1:
 - fix doc prototype mistake reported by the kernel test robot
 - preset page_size to 256 to support flashes which just have
   SFDP data corresponding to JESD216A
 - add new patch
   mtd: spi-nor: fix select_uniform_erase to skip 0 erase size
 - add function doc to explain wanted_size=0 in
   spi_nor_select_uniform_erase()

Michael Walle (7):
  mtd: spi-nor: hide jedec_id sysfs attribute if not present
  mtd: spi-nor: sysfs: hide manufacturer if it is not set
  mtd: spi-nor: remember full JEDEC flash ID
  mtd: spi-nor: move function declaration out of sfdp.h
  mtd: spi-nor: fix select_uniform_erase to skip 0 erase size
  mtd: spi-nor: add generic flash driver
  mtd: spi-nor: sysfs: print JEDEC ID for generic flash driver
