flashrom.8.tmpl: Clarify supported ft2232_spi frequencies
The manpage suggests that ft2232_spi chips are only capable of up to 12 MHz SPI clock frequencies, whereas flashrom disables the divide-by-5 prescaler on the 'H' chips allowing up to 60 MHz frequencies. This detail was already present in the comments of ft2232_spi.c.
