Subject: [PATCH v2 1/1] dt-bindings: timer: Add new OST support for the upcoming new driver.

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.
