Shawn Nematbakhsh 9c053ea898 mec1322: clock: Use full-speed 48MHz processor clock during EC boot 
EC boot / hash computing can be a bottleneck for system boot time.
Reduce this bottleneck by running our processor at 48 MHz through boot,
until vboot hashing of RW completes.

BUG=chrome-os-partner:49583
TEST=Boot chell, verify vboot hash completes within 1 sec of EC boot and
'cbmem' delta between 'vboot select&load kernel' and 'finished EC
verification' is reduced to ~250 ms (which includes sysjump time).
BRANCH=glados
