Fix support for the SIOCATMARK and SIOCGPGRP ioctls for eXtensa by
correcting corresponding macro definition.

Values for TARGET_SIOCATMARK and TARGET_SIOCGPGRP are determined by
Linux kernel. Following relevant lines are from kernel source tree:

arch/ia64/include/uapi/asm/sockios.h:#define SIOCATMARK    0x8905
arch/mips/include/uapi/asm/sockios.h:#define SIOCATMARK    _IOR('s', 7, int)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCATMARK  0x8905
arch/sh/include/uapi/asm/sockios.h:#define SIOCATMARK      _IOR('s', 7, int)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCATMARK  _IOR('s', 7, int)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCATMARK   _IOR('s', 7, int)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCATMARK   0x8905
include/uapi/asm-generic/sockios.h:#define SIOCATMARK	   0x8905

arch/ia64/include/uapi/asm/sockios.h:#define SIOCGPGRP     0x8904
arch/mips/include/uapi/asm/sockios.h:#define SIOCGPGRP     _IOR('s', 9, pid_t)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCGPGRP   0x8904
arch/sh/include/uapi/asm/sockios.h:#define SIOCGPGRP       _IOR('s', 9, pid_t)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCGPGRP   _IOR('s', 9, pid_t)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCGPGRP    _IOR('s', 9, pid_t)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCGPGRP    0x8904
include/uapi/asm-generic/sockios.h:#define SIOCGPGRP       0x8904

It is visible that eXtensa should have the same definitions as
alpha, mips and sh4 already do. This patch brings that to the
accurate state.

Hello, Xtensa folks!

This patch was devised while looking at some MIPS scenarios, but, in fact,
it affects Xtensa platform only (found by inspecting relevant Linux kernel
headers).

Could someone form Xtensa Ack ot Not-Ack this patch?

Sincerely, Aleksandar

xtensa is the official name of this architecture, please fix the spelling
here...
