soc/rtc_clk: fix loss of precision in estimation of XTAL frequency

RTC_FAST_CLK_FREQ_APPROX is defined as 8500000, so 0.5MHz part was lost
when dividing by MHZ. Since cal_val is 64-bit the parens can be removed.

With 40MHz XTAL for a nominal ESP32 chip, this fixes estimated XTAL
frequency from 38 to 40MHz.
