Brian Masney ecab081e7c openrisc: define arch-specific version of nop() 
[ Upstream commit 0dfffa5479 ]

When compiling a driver written for MIPS on OpenRISC that uses the nop()
function, it fails due to the following error:

    drivers/watchdog/pic32-wdt.c: Assembler messages:
    drivers/watchdog/pic32-wdt.c:125: Error: unrecognized instruction `nop'

The driver currently uses the generic version of nop() from
include/asm-generic/barrier.h:

    #ifndef nop
    #define nop()   asm volatile ("nop")
    #endif

Let's fix this on OpenRISC by defining an architecture-specific version
of nop().

This was tested by performing an allmodconfig openrisc cross compile on
an aarch64 host.
