board/freescale/mx6qsabrelite/README explain a procedure to update the SPI-NOR on the SabreLite board without Freescale manufacturing tool but following this procedure leads to both "sf erase" and "sf write" failing on a mx6qsabrelite board:
MX6QSABRELITE U-Boot > sf probe 1 MX6QSABRELITE U-Boot > sf erase 0 0x40000 SPI flash erase failed MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000 SPI flash write failed
This is because the chip-select 1 is wrong and the correct value is 0x7300.
Since commit c1173bd0 ("sf command: allow default bus and chip selects") the chip-select and bus arguments for the sf probe command are optional so let's just remove it and use "sf probe" instead.

Changes since v1: - Fix the description by explaining that the chip-select can be passed but the value "1" is wrong and is not strictly required; suggested by Stefano Babic.
