Subject: [PATCH v3 1/9] clk: bcm: kona: Move CLOCK_COUNT defines into the
 driver

CLOCK_COUNT defines for each CCU are stored in the DT binding header.
This is not correct - they are not used by device trees, only internally
by the driver.

Move the CLOCK_COUNT defines directly into the driver in preparation
for dropping them from the DT binding include.
