This commit:
- makes the GOP_DP (bit 9) gatable clock a child clock of the
SD_MMC_GOP (bit 18) clock, as it should have been. The clock for bit
18 was just named SD_MMC, but since it also covers the GOP block, it
is renamed SD_MMC_GOP.
- makes the MG (bit 5) gatable clock a child clock of the MG_CORE
clock (bit 6)

The Kconfig currently controlling compilation of this code is:
drivers/clk/mvebu/Kconfig:config ARMADA_CP110_SYSCON
drivers/clk/mvebu/Kconfig: bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in Armada
CP110 system controller driver. This commit introduces new
API and registration for all clocks in CP110 HW blocks.

Original commit, which added support for Armada CP110 system controller
used global variables for storing all clock information. It worked
fine for Armada 7k SoC, with single CP110 block. After dual-CP110 Armada 8k
was introduced, the data got overwritten and corrupted.
This patch fixes the issue by allocating resources dynamically in the
driver probe and storing it as platform drvdata.

Armada CP110 system controller comprises its own routine responsble
for registering gate clocks. Among others 'flags' field in
struct clk_init_data was not set, using a random values, which
may cause an unpredicted behavior.
This patch fixes the problem by resetting all fields of clk_init_data
before assigning values for all gated clocks of Armada 7k/8k SoCs family.

The Armada CP110 system controller provides, amongst other things, a
number of clocks for the platform: a small number of core clocks, and
then a number of gatable clocks, derived from some of the core
clocks. Those clocks are configured via registers of the CP110 System
Controller.
The CP110 is the other core HW block (next to the AP806) used in the
Marvel Armada 7K and 8K SoCs.
