ish: Use 64-bit hardware timer
ISH has native support for storing the hardware ticks in a 64-bit
integer. With CONFIG_HWTIMER_64BIT, we can use this instead of relying
on the periodic rollover interrupt.
BUG=b:133190570,chromium:976804
BRANCH=none
TEST=ran arcada_ish for more than 2³² μs, observed timer worked as
normal
