  1. QSPIFBlockDevice: Handle CR3NV[1] quirk on S25FS512S 

    Cypress S25FS512S's SFDP table suggests checking bit-1 of the register
25FS512S as part of configuration detection. This bit should equal 1
in order for configuration to be correctly determined, but it is 0 on
actual hardware. We add a quirk to work around this.

Note: In Mbed OS, vendor-specific quirks are handled in block devices,
and the SFDP class is agnostic of any quirks. So when the SFDP class
requests the value of CR3NV, we let QSPIFBlockDevice's SFDP reader
callback to set bit-1 of the output to 1 to allow the SFDP class to
work correctly.

  2. SFDP: Add support for multiple configurations and sector maps 

    A Sector Map Parameter Table contains a sequence of the following
descriptors:
* (Optional) configuration detection command descriptors, one for
each command to run to determine the current configuration. This
exists only if the flash layout is configurable.
* Sector map descriptors, one for each possible configuration. On
a flash device with a non-configurable layout, there is only one
such descriptor.

Previously we only supported the non-configurable case with a single
descriptor. This commit adds support for multiple configurations.
