[U-Boot] [PATCH 1/1] x86: qemu-x86 requires CONFIG_SYS_HZ=2000

[Heinrich Schuchardt]

The sleep command only provides correct timings for
CONFIG_SYS_HZ=2000 on qemu-x86_defconfig.

This can be tested with

    date && sleep 4 && date

Make CONFIG_SYS_HZ editable.
Set it in qemu-x86_defconfig to 2000.
