[patch 02/23] arm: tegra: Remove unused function which fiddles with irq_desc

[-- Attachment #1: arm-tegra.patch --]
[-- Type: text/plain, Size: 3314 bytes --]

These functions are unused and in the way of cleanups in the core
code. If you have special requirements vs. irqs and PM then please
talk to me. Access to the generic core internals is going away.
