Add support for SFDP (JESD216)
Similar to modules using the opaque programmer framework (e.g. ICH Hardware
Sequencing) this uses a template struct flashchip element in flashchips.c with
a special probe function that fills the obtained values into that struct.
This allows yet unknown SPI chips to be supported (read, erase, write) almost
as if it was already added to flashchips.c.
