  Add Intel ice PMD support on Windows.
Remove #include sys/ioctl header file as it is not needed.
Replace x86intrin.h with rte_vect.h to avoid __m_prefetchw conflicting
types.
Replace POSIX usleep() API with rte API.
Add a new macro for the access() API as the original function
has been deprecated on Windows.
Add extra cflags '-fno-asynchronous-unwind-tables'
to avoid MinGW build error:
	Error: invalid register for .seh_savexmm

Fyi, caught at the UNH lab:

ninja: build stopped: subcommand failed.

I suppose this is because "-fno-asynchronous-unwind-tables" is not
passed to the base driver cflags.
Bonus question: should we make this workaround global for mingw compilation?

Thanks for the log. We will send a fix by passing the cflag to the base 
driver in v2.

However, I am not able to reproduce this error on my system.

I tried using the same version as UNH lab has: gcc 8.1.0 "gcc 
(x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0"
