Currently, TI clock driver uses an encapsulated struct that is cast into
a void pointer to store all register addresses. This can be considered
as rather nasty hackery, and prevents from expanding the register
address field also. Instead, replace all the code to use proper struct
in place for this, which contains all the previously used data.

This patch is rather large as it is touching multiple files, but this
can't be split up as we need to avoid any boot breakage.

This is not needed outside the driver, so move it inside it and remove
the prototype from the public header also.

This will be needed to move some additional clockdomain functionality
under clock driver.

The 'mpurate' option, historically used for specifying an initial
MPU rate at boot, no longer has any effect due to the supporting
code being removed as it was 'wrong and dangerous' [1].

This patch removes the remaining dead code associated with the
__setup macros to avoid confusion and reduce bloat.

Errata i810 states that DPLL controller can get stuck while transitioning
to a power saving state, while its M/N ratio is being re-programmed.

As a workaround, before re-programming the M/N ratio, SW has to ensure
the DPLL cannot start an idle state transition. SW can disable DPLL
idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request
active by setting a dependent clock domain in SW_WKUP.

This errata impacts OMAP5 and DRA7 chips, so enable the errata for these.

With most of the clock code under clock driver already, the low-level
register access code, and the init code for the same, is no longer
needed outside the clock driver. Thus, these can be moved under clock
driver also.

As most of the clock driver code has migrated, these are no longer used
for anything. Thus remove these APIs completely.

We should avoid exporting data from drivers, instead use an API for
registering the clock low level operations.
