[U-Boot] Illegal use of FP ops in clock_ti814x.c

Dear Matt,

I hope you are the right person to address this to - if not, please help to redirect to the current responsible developer.

Function pll_sigma_delta_val() in arch/arm/cpu/armv7/am33xx/clock_ti814x.c incorrectly uses "float" data, which results in FP operations which are not permitted in U-Boot.

The actual computation appears simple enough so a rewrite of the code without using any floating point operations should be fairly easy, but I don't understand the actual logic of this code, so I'd rather leave this to someone who does.

Could you please help and clean up these three lines of code?

Thanks in advance.

Best regards,

Wolfgang Denk
