ENGR00295560 ARM:imx6sl:evk Add SPI NOR flash boot and access support
Add BSP codes to support SPI NOR flash read, write and erase by using
"sf" command.
In addition, add a new configuration "mx6slevk_spinor" for building
the uboot that can be booted from SPI NOR flash and stored the
environments variables in it.
