This commit adjusts the list of possible "Sample At Reset" values that
define the CPU clock frequency of the AP806 (part of Marvell Armada
7K/8K) to the values that have been validated with the production
chip. Earlier values were preliminary.

The Kconfig currently controlling compilation of this code is:
drivers/clk/mvebu/Kconfig:config ARMADA_AP806_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.

The Armada AP806 system controller, amongst other things, provides a
number of clocks for the platform: the CPU cluster clocks, whose
frequencies are found by reading the Sample At Reset register, one
fixed clock, and another clock derived from the fixed clock, which is
the one used by most peripherals in AP806.
The AP806 is one of the two core HW blocks used in the Marvell 7K/8K
SoCs.
