xilinx: board: Add support to pick bootscr flash offset/size from DT
Location of bootscript in flash can be specified via /options/u-boot DT
node by using bootscr-flash-offset and bootscr-flash-size properties.
Values should be saved to script_offset_f and script_size_f variables.
Variables are described in doc/develop/bootstd.rst as:
script_offset_f
SPI flash offset from which to load the U-Boot script, e.g. 0xffe000
script_size_f
Size of the script to load, e.g. 0x2000
Both of them are used by sf_get_bootflow() in drivers/mtd/spi/sf_bootdev.c
to identify bootscript location inside flash.
