Ivan Grokhotkov 7c584e80b0 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.

Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet.
