This is an initial implementation adding basic clocks, such as UART,
USI, I2C, WDT, ect. and their parent clocks. It is heavily based on the
Exynos850 clock driver at 'drivers/clk/samsung/clk-exynos850.c' which
was made by Sam Protsenko, thus the copyright and author lines were
kept.

Bus clocks are enabled by default as well to avoid hangs while trying to
access CMU registers.

Only the parts of CMU_TOP needed for CMU_CORE and CMU_PERI, a bit of
CMU_CORE, and most of CMU_PERI is implemented as of now.

Signed-off-by: David Virag <virag.david003@gmail.com>
---
Changes in v2:
  - Use shared code between Exynos850 and 7885 clock drivers
  - As the code that was from the Exynos850 clock driver was moved to
    clk-exynos-arm64.c and what remains is mostly SoC specific data,
    move the Linaro copyright and Sam Protsenko author lines there.

Changes in v3:
  - Nothing

Similarly to your previous patch - you need headers for every explicitly
used symbol/function etc.

Best regards,
