Subject: [PATCH V4 1/4] ARM: tegra30: clocks: Fix pciex clock registration

Registering pciex as peripheral clock instead of fixed clock
as tegra_perih_reset_assert(deassert) api of this clock api
gives warning and ultimately does not succeed to assert(deassert)

Patch is based on remotes/gitorious_thierryreding_linux/tegra/next and should be applied on top of this.

Changes in V4:
- Avoid modifying tegra pcie driver name for duplicate clocks as per review comments
