The SFDP functions parse SFDP data which is fetched by a callback
called `sfdp_reader` provided by {SPIF,QSPIF,OSPIF}BlockDevice.
Currently, this callback interface only takes a read address and an RX
buffer to store output data. This has been enough, because other SPI
parameters are always the same when fetching the SFDP table only -
they are just hardcoded in each reader.
But in the future we will add support for flash devices with multiple
configurations (in a subsequent commit), and to detect which
configuration is enabled, we will need to send detection commands
which require device-dependent SPI parameters:
* address size
* instruction
* dummy cycles
This commit
* turns the above SPI parameters from predefined/hardcoded values
into parameters of the callback
* lets the SFDP functions pass the above parameters to the callback
(Note: To read the SFDP table itself, those values are constants
defined by the standard, not tied to any particular device, so they
can be known to the SFDP functions)
* updates the callbacks implemented by {SPIF,QSPIF,OSPIF}BlockDevice
* updates the mock callback for unit tests and expectations
