sf: Drop spl_flash_get_sw_write_prot
The get_sw_write_prot API is used to get the write-protected
bits of flash by reading the status register and other wards
it's API for reading register bits.
1) This kind of requirement can be achieved using existing
flash operations and flash locking API calls instead of
making a separate flash API.
2) Technically there is no real hardware user for this API to
use in the source tree.
3) Having a flash operations API for simple register read bits
also make difficult to extend the flash operations.
4) Instead of touching generic code, it is possible to have
this functionality inside spinor operations in the form of
flash hooks or fixups for associated flash chips.
Considering all these points, this patch drops the get_sw_write_prot
and associated code bases.
