This undoes commit 20f46658 "ARM: tegra: remove tegra_timer from
tegra_list_clks" by bringing back the tegra_timer clock. tegra_timer is
indeed a clock (hidden by the PERIPH_CLK macro) which should be added
to the tegra_list_clks.

The above commit caused tegra_init_timer() failing to get the clk
reference.

The tegra_cpu_car_ops provide the interface for CPU to control
it's clock gating and reset status. The other drivers should use
this for CPU control. And should not directly access CAR registers
to control CPU.

Add connection name "div-clk" for the i2c clock entry.
Signed-off-by: NLaxman Dewangan <ldewangan@nvidia.com>
Signed-off-by: NStephen Warren <swarren@nvidia.com>

Tegra's i2c controller require two clock sources named as
div-clk and fast-clk for proper operation.
Currently, the entry of fast-clk is missing in tegra30
clock table and it is incorrectly named in the tegra20
clock table.
Adds aliases to enable lookups for "fast-clk" to succeed.
A later patch will remove the incorrectly named clock,
once the driver is modified to use the new name.

tegra_time is a struct sys_timer, not a struct clk, so can't be included

It should use tegra30_audio_sync_clk_ops for tegra30. It will cause
the tegra30 use the wrong audio_sync_clk_ops when build a kernel with
a tegra20 and tegra30 both supported kernel. And building error when
a tegra30-only kernel.

Currently the tegra20 and tegra30 share the same symbol for
tegra_clk_32k_ops. This will cause a compile error when building
a tegra20-only kernel image. Add tegra_clk_32k_ops for tegra20 and
modify tegra30_clk_32k_ops for tegra30.

This patch converts tegra clock code to generic clock framework in following way:
 - Implement clk_ops as required by generic clk framework. (tegraXX_clocks.c)
 - Use platform specific struct clk_tegra in clk_ops implementation instead of struct clk.
 - Initialize all clock data statically. (tegraXX_clocks_data.c)

Legacy framework did not have recalc_rate and is_enabled functions. Implemented these functions.
Removed init function. It's functionality is splitted into recalc_rate and is_enabled.

Static initialization is used since slab is not up in .init_early and clock
is needed to be initialized before clockevent/clocksource initialization.
Macros redefined for clk_tegra.

Also, single struct clk_tegra is used for all type of clocks (PLL, peripheral etc.). This
is to move quickly to generic common clock framework so that other dependent features will
not be blocked (such as DT binding).

Enabling COMMON_CLOCK config moved to ARCH_TEGRA since it is enabled for both Tegra20
and Tegra30.
