Added SPL_AC_5ARGS_DEVICE_CREATE autoconf configure check

Browse Source 
As of 2.6.27 kernels the device_create() API changed to include
a private data argument.  This check detects which version of
device_create() function the kernel has and properly defines
spl_device_create() to use the correct prototype.
