[PATCH 8/9] ARM: dts: broadcom: Identify the NSP EHCI controller

[Florian Fainelli]

The NSP SDK programs the EHCI FIFO threshold to 0x00800040, but the
upstream device tree describes the controller only as generic-ehci.
This prevents ehci-platform from selecting the required initialization.

Add the NSP compatible to select its FIFO threshold workaround while
retaining generic-ehci as a fallback.

Fixes: 1d8ece6639e1 ("ARM: dts: NSP: Add EHCI/OHCI USB nodes to device tree")
