[PATCH V2 5/6] HACK: arm: tegra: reuse the Tegra114 clock driver for Tegra124

[Joseph Lo <josephl-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

This patch is only a hack for Tegra124 bring up testing. Please don't
merge this. The same function can be replaced by Tegra124 clock driver.

* re-use UART-A in DT
* add a temp PMC compatible value
