Return the correct value when the speed grade is 696MHz.
This makes U-Boot to print the correct value at boot:

U-Boot 2017.09-rc1-dirty (Aug 02 2017 - 12:02:26 +0200)

CPU:   Freescale i.MX6ULL rev1.0 696 MHz (running at 396 MHz)

instead of

U-Boot 2017.09-rc1-dirty (Aug 02 2017 - 11:47:51 +0200)

CPU:   Freescale i.MX6ULL rev1.0 69 MHz (running at 396 MHz)

Thanks. However, I've just noticed this is only true for i.MX6UL.
i.MX6ULL has different speed grading.

Should I resend my patch and fix the commit log?
