spi: fsl-qspi: introduce sfa_size devtype data

In fsl_qspi_default_setup(), four registers define the size of blocks of
data to written to each of four chips that comprise SPI NOR flash storage.
They are currently defined to be the same as the AHB buffer size.

The SpacemiT QSPI has an AHB buffer size of 512 bytes, but requires these
four sizes to be multiples of 1024 bytes.

Define a new field sfa_size in the fsl_qspi_devtype_data structure that, if
non-zero, will be used instead of the AHB buffer size to define the size of
these chip regions.
