libpayload: timer: Move the timer drivers from depthcharge to libpayload.

These drivers are needed right away and never really fit into depthcharge's
driver model anyway.

CQ-DEPEND=CL:194064
BUG=None
TEST=Built and booted nyan, link, and peach_pit and verified that timer values
in cbmem were reasonable. Built for nyan_big, nyan_blaze and daisy.
BRANCH=None
