Devyn LiuandGreg Kroah-Hartman 8b28f8c5d1 spi: hisi-kunpeng: Add validation for the minimum value of speed_hz 
[ Upstream commit c3c4f22b7c ]

The speed specified by the user is used to calculate the clk_div based
on the max_speed_hz in hisi_calc_effective_speed.  A very low speed
value can lead to a clk_div larger than the variable range. Avoid this
by setting the min_speed_hz so that such a small speed value is
rejected.  __spi_validate() in spi.c will return -EINVAL for the
specified speed_hz lower than min_speed_hz.
