Sifan Naeem 6a806a214a spi: img-spfi: fix support for speeds up to 1/4th input clock 
Setting the Same Edge bit indicates to the spfi block to receive and
transmit data on the same edge of the spfi clock, which in turn
doubles the operating frequency of spfi.

The maximum supported frequency is limited to 1/4th of the spfi input
clock, but without this bit set the maximum would be 1/8th of the
input clock.

The current driver calculates the divisor with maximum speed at 1/4th
of the input clock, this would fail if the requested frequency is
higher than 1/8 of the input clock. Any requests for 1/8th of the
input clock would still pass.
