rk3288: Allow board-specific APLL (CPU clock) settings
This changes the API to rkclk_configure_cpu() such that we can pass in the desired APLL frequency in each veyron board's bootblock.c. Devices with a constrainted form facter (rialto and possibly mickey) will use this to run firmware at a slower speed to mitigate risk of thermal issues (due to the RK808, not the RK3288). BUG=chrome-os-partner:42054 BRANCH=none TEST=amstan says rialto is noticably cooler (and slower) Change-Id: I28b332e1d484bd009599944cd9f5cf633ea468dd Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: d10af5e18b4131a00f202272e405bd22eab4caeb Original-Change-Id: I960cb6ff512c058e72032aa2cbadedde97510631 Original-Signed-off-by: David Hendricks <dhendrix@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/297190 Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-on: http://review.coreboot.org/11582 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
