[PATCH 1/6] staging: vc04_services: Convert dsb() to dsb(sy)

[mzoran at crowfest.net]

From: Michael Zoran <mzoran at crowfest.net>

The dsb() macro for 32 arm compiles to dsb(sy) in the binary file.
This macro is no longer supported on arm64, so instead use dsb(sy)
which is completely binary compatible.
