Tero Kristo ab7b2ffcf5 ARM: OMAP2+: PRM: move SoC specific init calls within a generic API
This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

Tero Kristo 61c8621e2b ARM: OMAP2+: PRM: provide generic API for system reset
This patch combines the various prm_warm_reset calls under a common
API prm_reset_system, and adds the SoC specific implementation under
prm_ll_data.

Tero Kristo 85d6670f1b ARM: AM33xx: PRM: make direct register access functions static
These should not be accessed outside driver, thus removed the APIs
from the header file and made the implementation static.

Tero Kristo 1bc28b3472 ARM: OMAP2+: PRM: add generic API for checking hardreset status
PRM driver now has a generic API for checking hardreset status. SoC
specific support functions are registered through the prm_ll_data.

Tero Kristo d9bbe84f67 ARM: AM33xx: PRM: add support for prm_init
Added support for prm_init for AM33xx SoC. This is needed to register
SoC specific prm_ll_data for these devices.

Vaibhav Hiremath ddd04b989f ARM: OMAP AM33xx: PRM: add PRM support
As far as PRM/CM/PRCM modules are concerned, AM33XX device is
different than OMAP3 and OMAP4 architectures; so we need to handle it
separately.  This patch adds support for the PRM APIs required for
AM33XX device.
