soc/amd/common: Change default spi speeds to 33MHz

Browse source 
In CB:56884 we discussed changing the default fast_read speed from
66MHz, which some platforms may not be capable of running, to 33MHz,
which should be generally suitable for all platforms.  This same
change has been applied to the default for all SPI speeds.
