phaser: enable phaser motion sensor drivers
This patch add phaser base and lid accel sensor support.
Lid sensor type is lis2de, it has the same register interface
as lis2dh, so they share the same driver. Since it has a very
small fifo, use it in forced mode.

BRANCH=none
BUG=b:110013316
TEST=boot phaser board, base and lid sensor can be inititalized
successfully. use console command "accelinfo on", both
sensors has valid output.
