NVIDIA: SAUCE: usb: host: tegra: Remove manual wake IRQ disposal

Browse Source 
We found that calling irq_dispose_mapping() caused a kernel warning
when removing the driver. The IRQs are obtained using
platform_get_irq(), which returns a Linux virtual IRQ number directly
managed by the device core, not by the OF subsystem. Therefore, the
driver should not call irq_dispose_mapping() for these IRQs.

Bug 5421820
