cpufreq: make ti-cpufreq explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/cpufreq/Kconfig.arm:config ARM_TI_CPUFREQ
drivers/cpufreq/Kconfig.arm:    bool "Texas Instruments CPUFreq support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
