This patchset does the following:

- Introduce support for bus clocks. These are fairly similar to
  peripheral clocks, but only implement policy, gate and hyst.

- Add matching bus clocks for BCM21664 and BCM281xx peripheral clocks
  and update device tree bindings to match.

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. To avoid conflicts with
the old defines, rename them to use the CLK_COUNT suffix.

The CLOCK_COUNT defines are not used by device trees, only by the clock
driver. Keeping them in the DT binding header is frowned upon.

Since they're being moved to the clock driver directly, drop these defines
from the dt-bindings header and only keep clock IDs.

Add bus clocks corresponding to peripheral clocks currently supported
by the BCM21664 and BCM281xx clock drivers and add the relevant clock
IDs to the dt-bindings headers (bcm21664.h, bcm281xx.h).

Fix a warning raised by checkpatch about non-const clk_ops by making the
relevant struct const.

Introduce support for bus clocks into the Broadcom Kona common clock
driver. Most of these functions have been adapted from their peripheral
clock counterparts, as they are nearly identical (bus clocks are just
much more limited in terms of allowed operations).

Now that bus clock support has been implemented into the Broadcom Kona
clock driver, add bus clocks corresponding to HUB_TIMER, SDIO, UART and
BSC, as well as the USB OTG bus clock.

Signed-off-by: Artur Weber <aweber.kernel@gmail.com>

Changes in v4:
- Adapt to CLOCK_COUNT -> CLK_COUNT rename
- Change commit summary to match equivalent BCM281xx commit

Changes in v3:
- Adapt to CLOCK_COUNT defines being moved

Changes in v2:
- Adapt to dropped prereq clocks

Following changes in the clock driver, add bus clocks for timer, SDIO,
BSC and UART to the DTS clock output names. Replace the usb_otg_ahb
fixed clock with the real bus clock.

Following changes in the clock driver, add matching bus clocks for
existing peripheral clocks. Replace the usb_otg_ahb fixed clock with
the real bus clock.
