Use macro IO_ADDRESS for getting virtual address of
corresponding physical address to make the consistency
with rest of Tegra code-base.
This macro calls the IO_TO_VIRT() which is defined in
arch/arm/mach-tegra/include/mach/iomap.h

The powergating and reset handling code needs to differentiate between Tegra
variants. Therefore we export the chipid here.

The chipid register contains information about the Tegra variant and revision.
We want differentiate between Tegra variants for powergating and secondary
core bringup. This patch cleans up the reading and decoding of this register.
In subsequent patches the variant will exported as a global variable.

This is used by the memory setup code to pick the right memory
timing table, if needed.

Add function to get chip revision, and print it out at boot time.

Restructure the fuse access to just use cached variables instead
of always reading the fuses, and export those variables directly
instead of using accessor functions.

Add a SKU ID table of currently known values.

Based on code originally by Colin Cross <ccross@android.com>.

Changes since v1:

* Add A01 minor rev support
* Don't decode for A03p on anything but T2x

Use the apbio dma functions for accessing the fuse registers.

The crypto driver will need this api to use
it in the RNG calculations. In order to build
the crypto driver as a module, tegra_chip_uid
has to be exported.

The Tegra SOC contains fuses to identify the CPU type and
bin, and a unique id.  The CPU info is required to determine
the correct voltages for each cpu and core frequency.
