Subject: [PATCH v2 3/6] ARM: dts: NSP: Fix SP804 compatible node

The DT binding for SP804 requires to have an "arm,primecell" compatible
string.
Add this string so that the Linux primecell bus driver picks the device
up and activates the clock.

Fixes: a0efb0d28b77 ("ARM: dts: NSP: Add SP804 Support to DT")
Tested-by: Florian Fainelli <f.fainelli@...il.com>
