The new OST has one global timer and two or four percpu timers, so there
will be three combinations in the upcoming new OST driver: the original
GLOBAL_TIMER + PERCPU_TIMER, the new GLOBAL_TIMER + PERCPU_TIMER0/1 and
GLOBAL_TIMER + PERCPU_TIMER0/1/2/3, For this, add the macro definition
about OST_CLK_PERCPU_TIMER0/1/2/3. And in order to ensure that all the
combinations work normally, the original ABI values of OST_CLK_PERCPU_TIMER
and OST_CLK_GLOBAL_TIMER need to be exchanged to ensure that in any
combinations, the clock can be registered (by calling clk_hw_register())
from index 0.
