Current Tegra clock driver registers PMC clocks clk_out_1, clk_out_2,
clk_out_3 and blink output in tegra_pmc_init() which does direct Tegra
PMC access during clk_ops and these PMC register read and write access
will not happen when PMC is in secure mode.

Any direct PMC register access from non-secure world will not go
through and all the PMC clocks and blink control are done in Tegra PMC
driver with PMC as clock provider.

This patch removes tegra_pmc_clk_init along with corresponding clk ids
from Tegra clock driver.

Perhaps these clocks do not need to be always-enabled?

Also, EXTERN1 parent configuration should be moved to the audio
driver/device-tree as well.

Maybe it even makes sense to move the whole configuration, including
PLLA. I don't see why clk driver need to do something for the audio driver.

Ah, I missed that it's done in the patch #10.

I2S could use assigned-clocks, but probably it's not really necessary
and predefined configuration in the clk driver is good enough.

At least PLLA doesn't need to be always-enabled since audio drivers
enable it when necessary.
