soc/amd/picasso: Introduce enums for SPI read mode and speed

This change adds enums for spi_read_mode and spi100_speed in
preparation for adding these to chip.h in follow-up CLs. This makes it
easier to reference what the mainboard is expected to set for these
SPI configs.

BUG=b:147758054,b:153675510
BRANCH=trembyle-bringup
TEST=Verified that SPI configuration is correct for trembyle.
