mtd: spi-nor: swp: Create a helper that writes SR, CR and checks

There are many helpers already to either read and/or write SR and/or CR,
as well as sometimes check the returned values. In order to be able to
switch from a 1 byte status register to a 2 bytes status register while
keeping the same level of verification, let's introduce a new helper
that writes them both (atomically) and then reads them back (separated)
to compare the values.

In case 2 bytes registers are not supported, we still have the usual
fallback available in the helper being exported to the rest of the core.
