mtd: spi-nor: fix spi_nor_spimem_setup_op() call in spi_nor_erase_{sector,chip}()
For erase operations, reg_proto must be used as indicated in
struct spi_nor description in spi-nor.h.
This issue was found when DT property spi-tx-bus-width is set to 4.
In this case the spi_mem_op->addr.buswidth is set to 4 for erase command
which is not correct.
Tested on stm32mp157c-ev1 board with mx66l51235f spi-nor.
Fixes: 0e30f47232ab ("mtd: spi-nor: add support for DTR protocol")
