Default setting is at 48MHz. For PLL frequency at 24MHz: 1. USB module can't work, it requires 48MHz to work. 2. SSPI clock frequency is divide by two. Signed-off-by: Dino Li <dino.li@ite.com.tw> BRANCH=none BUG=none TEST=1. uart, i2c, timer, and pd modules are function normally at different PLL frequency settings. 2. use 'flashrom' utility to flash EC binary with different PLL settings.
