[meta-xilinx] [PATCH] board-common.cfg: Disable 4K sectors on QSPI NOR flash

[Mike Looijmans]

The 4K sector support makes erasing much slower and prevents using
wear-levelling filesystems like UBI, which needs erase sectors to be
at least 16k in size. Until this situation has been properly resolved
in the kernel, disable the setting.
